Exhibitionism is the act of exposing in a public or semi-public context one's intimate parts – for example, the breasts, genitals or buttocks.
It refers to an uncontrollable urge to exhibit one's genitals to an unsuspecting stranger, and is called an "Exhibitionistic Disorder" rather than simply exhibitionism.
The practice may arise from a desire or compulsion to expose oneself in such a manner to groups of friends or acquaintances, or to strangers for their amusement or sexual satisfaction, or to shock the bystander.
[6] In the United Kingdom, the 4th draft of the revised Vagrancy Act 1824 included an additional clause "or openly and indecently exposing their persons" which gave rise to difficulties because of its ill-defined scope.
[7] The development of new technologies such as smartphones and tablets has permitted some exhibitionists to reorient their methods such as with nude selfies.
[12] 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?"
