Exhibitionism is the act of exposing in a public or semi-public context those parts of one's body that are not normally exposed – for example, the breasts, genitals or buttocks. The practice may arise from a desire or compulsion to expose themselves in such a manner to groups of friends or acquaintances, or to strangers for their amusement or sexual satisfaction or to shock the bystander. Exposing oneself only to an intimate partner is normally not regarded as exhibitionism. In law, the act of exhibitionism may be called indecent exposure, "exposing one's person", or other expressions.


Women "flashing", or publicly exposing their bare breasts, at Woodstock Festival Poland, 2011

Public exhibitionism by women has been recorded since classical times, often in the context of women shaming groups of men into committing, or inciting them to commit, some public action. The ancient Greek historian Herodotus gives an account of exhibitionistic behaviors from the fifth century BC in The Histories. Herodotus writes that:

When people travel to Bubastis for the festival, this is what they do. Every baris carrying them there overflows with people, a huge crowd of them, men and women together. Some of the women have clappers, while some of the men have pipes which they play throughout the voyage. The rest of the men and women sing and clap their hands. When in the course of their journey they reach a community — not the city of their destination, but somewhere else — they steer the bareis close to the bank. Some of the women carry on doing what I have already described them as doing, but others shout out scornful remarks to the women in the town, or dance, or stand and pull up their clothes to expose themselves. Every riverside community receives this treatment.

A case of what appears to be exhibitionism in a clinical sense was recorded in a report by the Commission against Blasphemy in Venice in 1550.

In the UK the 4th draft of the revised Vagrancy Act of 1824 included an additional clause 'or openly and indecently exposing their persons' which gave rise to difficulties because of its ill-defined scope. During the course of a subsequent debate on the topic in Parliament, the then Home Secretary, Mr Peel, observed that 'there was not a more flagrant offence than that of indecently exposing the person which had been carried to an immense extent in the parks...wanton exposure was a very different thing from accidental exposure'.

The development of new technologies such as smartphones and tablets has permitted some exhibitionists to reorient their methods such as with nude selfies.

Psychological aspects

Charles Lasègue was the first to use the term exhibitionist, in 1877.

The term exhibitionist was first used in 1877 by French physician and psychiatrist Charles Lasègue. Various earlier medical-forensic texts discuss genital self-exhibition, however.

When exhibitionistic sexual interest is acted on with a non-consenting person or interferes with a person's quality of life or normal functioning, it can be diagnosed as exhibitionistic disorder in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). The DSM states that the highest possible prevalence for exhibitionistic disorder in men is 2% to 4%. It is thought to be much less common in women. In a Swedish survey, 2.1% of women and 4.1% of men admitted to becoming sexually aroused from the exposure of their genitals to a stranger.

A research team asked a sample of 185 exhibitionists, "How would you have preferred a person to react if you were to expose your privates to him or her?" The most common response was "Would want to have sexual intercourse" (35.1%), followed by "No reaction necessary at all" (19.5%), "To show their privates also" (15.1%), "Admiration" (14.1%), and "Any reaction" (11.9%). Only very few exhibitionists chose "Anger and disgust" (3.8%) or "Fear" (0.5%).

Types of exposure

Various types of behavior are classified as exhibitionism, including:

  • Anasyrma: the lifting of the skirt when not wearing underwear, to expose genitals.
  • Candaulism: when a person exposes his or her partner in a sexually provocative manner.
  • Flashing: the momentary display of bare female breasts by a woman with an up-and-down lifting of the shirt or bra or the exposure of a man's or woman's genitalia.
  • Martymachlia: a paraphilia which involves sexual attraction to having others watch the execution of a sexual act.
  • Mooning: the display of bare buttocks by pulling down of trousers and underwear. The act is most often done for the sake of humour, disparagement, or mockery.
  • Reflectoporn: the act of stripping and taking a photograph using an object with a reflective surface as a mirror, then posting the image on the Internet in a public forum. Examples include "images of naked men and women reflected in kettles, TVs, toasters and even knives and forks". The instance generally credited with starting the trend involved a man selling a kettle on an Australian auction site featuring a photograph where his naked body is clearly visible; other instances followed, and the specific term "reflectoporn" was coined by Chris Stevens of Internet Magazine.
  • Streaking: the act of running naked through a public place. The intent is not usually sexual but for shock value.
  • Sexting: the act of sending, receiving, or forwarding sexually explicit messages, photographs, or videos.
  • Telephone scatologia: the act of making obscene phone calls to random or known recipients. Some researchers have claimed that this is a variant of exhibitionism, even though it has no in-person physical component.

The DSM-5 diagnosis for exhibitionistic disorder has three subtypes: exhibitionists interested in exposing themselves to non-consenting adults, to prepubescent children, or to both.

Streaking is the act of running nude through a public area for publicity, as a prank, a dare, or a form of protest. Streaking is often associated with sporting events, but can occur in more secluded areas. Streakers are often pursued by sporting officials or the police.


Historical forerunners of modern-day streakers include the neo-Adamites who travelled naked through towns and villages in medieval Europe, and the 17th-century Quaker Solomon Eccles who went nude through the City of London with a burning brazier on his head. At 7:00 PM on 5 July 1799, a man was arrested at the Mansion House, London, and sent to the Poultry Compter. He confirmed that he had accepted a wager of 10 guineas (equal to £1,039 today) to run naked from Cornhill to Cheapside.

Fines of between £10 and £50 were imposed on streakers by British and Irish magistrates in the early 1970s. The offences used for prosecution were typically minor, such as the violation of park regulations. Nevertheless, the chief law in force against streaking in England and Wales at that time remained the 16th-century vagrancy law, for which the punishment in 1550 had been whipping.

Definitions and etymology

The word has been used in its modern sense only since the 1960s. Before that, to streak in English since 1768 meant "to go quickly, to rush, to run at full speed", and was a re-spelling of streek: "to go quickly" (c.1380); this in turn was originally a northern Middle English variant of stretch (c. 1250).

The term "streaking" was popularized by a reporter for a local Washington, D.C. news station as he watched a "mass nude run" take place at the University of Maryland in 1973. That nude run had 533 participants. As the collected mass of nude students exited Bel Air dorm, the reporter, whose voice was broadcast live over the station via a pay phone connection exclaimed... "they are streaking past me right now. It's an incredible sight!" The next day it was out on the Associated Press wire as "streaking" and had nationwide coverage.

On college campuses

The first recorded incident of streaking by a college student in the United States occurred in 1804 at Washington College (now Washington and Lee University) when senior George William Crump was arrested for running naked through Lexington, Virginia, where the university is located. Robert E. Lee later sanctioned streaking as a rite of passage for young Washington and Lee gentlemen. Crump was suspended for the academic session, but later went on to become a U.S. Congressman.

In 1973, the media reported that a "streaking epidemic" had hit Stephen F. Austin State University in Nacogdoches, Texas, with streakers being seen in residence halls, at football games and at various other on-campus locations and events, including spring graduation. The trend continued until spring 1974, when university president Ralph W. Steen—hoping to end the streaking fad—designated a day to streak the length of East College Street. The "epidemic" was covered by all of the major media outlets and became the first time streaking received concentrated national press coverage, including an article in Paris Match covering the phenomenon.

In December 1973, Time magazine called streaking "a growing Los Angeles-area fad" that was "catching on among college students and other groups". A letter writer responded, "Let it be known that streakers have plagued the campus police at Notre Dame for the past decade", pointing out that a group of University of Notre Dame students sponsored a "Streakers' Olympics" in 1972.

Colleges and universities with documented traditions of campus streaking include the University of Chicago (Polar Bear run), Denison University (Naked Week), Oberlin College, Pennsylvania State University, Wellesley College, and Wheaton College (the "Kingdom Run").

A 1967 article in the student newspaper at Carleton College described the streaking phenomenon there in negative terms, associating it with rock culture, drinking and destruction. At that time, streaking was a tradition on the Northfield, Minnesota, campus during January and February when temperatures hovered in the neighborhood of zero degrees Fahrenheit. According to The Carletonian: "Examples of [Carleton's social problems] are the large number of departing female students, the rise of class spirit, low grades, streaking, destruction, drinking, and the popularity of rock dances."

Dartmouth College has two streaking-related challenges: The Ledyard Challenge, in which students swim naked across the Connecticut River and run nude back across the bridge, and the Blue Light Challenge, in which streaking students attempt to press the alarm on every one of the campus's blue light emergency phones. As of 2005, a Thursday Night Streaking Club regularly streaks at various events and public places.

In 1986, the University of Michigan's Naked Mile celebrated the last day of class with a group streak across campus along an approximate one-mile path. At the height of its popularity in the late 1990s, between 500 and 800 students participated, including several hundred females. Over 1,400 students participated one year and well over one thousand during another year. However, due to enforcement of public indecency laws and pressure from administration officials concerned about increasing spectator crowds and videotaping, participation declined. By 2001, a mere 24 students participated, signaling the effective end of the Naked Mile. Students were warned by college administrators that streakers would be arrested and required to register as sex offenders for life under Megan's Law.

The students at Union College held midnight "Pajama Parade" events in 1862, 1914 and several times in the 1950s. The real streaking tradition, which was nationally popular since 1973, arrived at the campus in the 1990s in the form of a nocturnal lap around the Nott Memorial known as the "Naked Nott Run."

To celebrate the school year's first night of heavy rainfall, a well-known tradition called "First Rain" is enacted at the University of California, Santa Cruz by students who for the entirety of the day to midnight, run around campus nearly or completely nude. Beginning at Porter, the run proceeds throughout the other colleges.

At the University of Vermont, a Naked Bike Ride is traditionally held at midnight at the end of each semester. Participants run, bike, unicycle, carry kayaks, push shopping carts, or pull sleds. The topic of the Naked Bike Ride has been a touchy one among UVM police, who have tried several times to do away with it. In 2011, Interim President John Bramley ended school funding for the event. This resulted in the student body creating the UVM Green Caps, a group of student volunteers stationed around campus throughout the evening for the safety of students.

At the University of the Philippines, members of the Alpha Phi Omega fraternity streak around the campus in an annual event known as the Oblation Run. The run started in 1977 to protest the banning of the movie, "Hubad na Bayani", which depicted human rights abuses in the martial law era. The event continued to occur as a protest action.

In 2011, the first nudist race took place at the University of Alicante (Spain).

In sport

The first instance of streaking in English football took place on March 23, 1974. Prior to the start of the league match between Arsenal and Manchester City at Highbury, a middle aged man named John Taylor ran around the field. He was eventually caught by three policemen, forcibly made to wear trousers, and removed from the stadium. Taylor was fined £10 by the North London Court the next day.

In the sport of cricket, it is not uncommon for a male streaker to run out to the field purely for shock and entertainment value or political purposes. The first known instance of streaking in cricket took place on 22 March 1974, the first day of the third test between Australia and New Zealand at Auckland. Half an hour before the end of the day's play, while New Zealand was batting, "a dark-haired young man" ran from near the sightscreen, through mid-wicket and disappeared between the stands near the square-leg boundary. The incident occurred quickly and police did not have time to react. Reports differ on whether the man was completely naked, with some accounts stating that he may have been wearing a flesh-coloured T-shirt. On the evening of the second day, while Australian batsman Ian Redpath was on strike, an "athletic young man" was caught on television cameras running across the ground on the leg-side. The streaker ran to the men's restroom and was chased by police. When police entered the restroom, they found 20 people inside--all of whom were clothed. Authorities were unable to identify the streaker. One of the best-known instances of streaking occurred on 5 August 1975, when former Royal Navy cook Michael Angelow ran naked across Lord's during an Ashes Test. This was the first instance of streaking during a cricket match in England, and commonly mistakenly believed to be the first ever instance of streaking in cricket.

Another example was in the First Test of the Australia versus the I.C.C. World XI, when a rather drunken man darted out toward the field naked, shocking the Australian and World XI players, halting play until he was spear tackled to the ground by field personnel. In one notable incident in 1977, Australian test cricketer Greg Chappell spanked an invading streaker named Bruce McCauley with his cricket bat; McCauley then fell to the ground and was arrested by police.

The English glamour model Linsey Dawn McKenzie performed a topless streak at a televised England v. West Indies cricket match at Old Trafford in 1995. Wearing only a thong and a pair of trainers, she ran onto the field with the words "Only Teasing" written across her breasts.

In the 1970s, at the height of streaking's popularity, a male streaker who broke into the Augusta National golf course in Augusta, Georgia (albeit not while the Masters was in play) was shot with buckshot and slightly wounded. In 1999, a female streaker named Yvonne Robb was arrested for kissing Tiger Woods on the 18th hole at Carnoustie.

Streaking became popular at Australian rules football matches in the 1980s, particularly Victorian Football League Grand Finals. The trend was a trend started by Adelaide stripper Helen D'Amico at the 1982 VFL Grand Final between Carlton and Richmond, in which D'Amico streaked while wearing only a Carlton scarf. At the 1988 VFL Grand Final, a fully naked woman streaked during the final quarter and was promptly arrested.

In Super Bowl XXXVIII, streaker Mark Roberts disrupted the game by running onto the field. He was eventually leveled by New England Patriots linebacker Matt Chatham, and was subsequently apprehended. Despite the worldwide audience, this event was largely unnoticed due to that game's infamous halftime show in which Janet Jackson's nude breast was revealed due to what was called a "wardrobe malfunction". Roberts would return in 2007 during the first NFL regular season game held in England between the Miami Dolphins and New York Giants, streaking during the game at Wembley Stadium.

In the 2006 Winter Olympics, streaker Mark Roberts interrupted the men's bronze medal curling match between the U.S. team and the UK team, wearing nothing but a strategically placed rubber chicken. For the 2008 Olympics in Beijing, officials warned visitors against streaking, amongst other forms of "bad behaviour".

Michael O'Brien was the first known streaker at a major sporting event when on 20 April 1974, he ran out naked onto the ground of an England vs. France rugby union match at Twickenham. The 25-year-old Australian was captured by a policeman, PC Bruce Perry, who covered his genitals with his police helmet. The photograph of O'Brien under arrest became one of the most reproduced photographs of a streaker.

On 22 March 2009, a female streaker ran onto the pitch brandishing a green flag during the televised match between London Irish and Northampton Saints. It was in front of the season's largest crowd away from Twickenham, 21,000 fans bearing witness.

In a game against the Melbourne Storm at Olympic Park in 2007, a Brisbane Broncos fan streaked across the field waving his supporter jersey over his head. He was apprehended at the other side of the field to large applause.

During an NRL finals match between the Wests Tigers and the New Zealand Warriors at the Sydney Football Stadium on 16 September 2011, a streaker ran onto the playing field forcing the game to come to a halt as security guards attempted to apprehend the man.

During the final minutes of the third and deciding game of the 2013 State of Origin series, a streaker, Wati Holmwood, intruded naked upon the field, interrupting the play and possibly costing the Queensland team a try. He was tackled by security guards, escorted from the field and fined $5,500.

In popular culture

The high point of streaking's pop culture significance was in 1974, when thousands of streaks took place around the world. A wide range of novelty products were produced to cash in on the fad, from buttons and patches to a wristwatch featuring a streaking Richard Nixon, to pink underwear that said "Too shy to streak." The prominence of streaking in 1974 has been linked both to the sexual revolution and a conservative backlash against feminism and the campus protests of the late 1960s and early 1970s.

Perhaps the most widely seen streaker in history was 34-year-old Robert Opel, who streaked across the stage of The Dorothy Chandler Pavilion in Los Angeles flashing a peace sign on national US television at the 46th Academy Awards in 1974. Bemused host David Niven quipped, "Isn't it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings?" Later, evidence arose suggesting that Opel's appearance was facilitated as a publicity stunt by the show's producer Jack Haley Jr.. Robert Metzler, the show's business manager, believed that the incident had been planned in some way; during the dress rehearsal Niven had asked Metzler's wife to borrow a pen so he could write down the famous line, which was thus not the ad-lib it appeared to be.

Ray Stevens wrote and performed "The Streak", a novelty song about a man who is "always making the news / wearing just his tennis shoes". The song reached number one on the Billboard Hot 100 in May 1974.

In 2014, Russian project ChaveZZZ Reality released a single "Naked Runner" and a same-titled video-clip specifically dedicated to all streakers worldwide.

In Bruce Weber's 2014 account of a bike ride across America Life is a Wheel he recounts a memory of his friend Billy streaking across the campus of Clark University at the age of 18.

In 2019 the comic novella "Confessions of a Flash Artist" by Renald Iacovelli explored exhibitionism as an avant-garde art form.


As of 2004, the record for the largest group streak was established at the University of Georgia with 1,543 simultaneous streakers on March 7, 1974.
