Indecent exposure : Exhibitionism

Indecent exposure is the display of one's genitalia (in the case of a man: with or without erection) in an environment where this isn't considered socially acceptable.

This behavior is a criminal offence in many jurisdictions, and is regarded as a sex crime.

In some jurisdictions, indecent exposure, even without erection, differs from mere public nudity, in that the intent of the former is often to shock or harass. In most jurisdictions there is a very thin line (if any) between these two behaviors.

Those who expose themselves are colloquially known as "flashers".

An urge to behave like this is a paraphilia, called exhibitionism.

In the United States, laws governing the definition of and punishment for indecent exposure vary from state to state.

Mooning is usually considered a mild form of indecent exposure.
