n. the crime of displaying one's genitalia to one or more other people in a public place, usually with the apparent intent to shock the unsuspecting viewer and give the exposer a sexual charge.
Revealing one's genitals under circumstances likely to offend others. Exposure is indecent under the law whenever a reasonable person would or should know that his act may be seen by others--for example, in a public place or through an open window--and that it is likely to cause affront or alarm. Indecent exposure is considered a misdemeanor in most states.
Indecent exposure is the display of bare parts of the human body that, according to the standards of the local cultural norms, would otherwise be clothed. In most public places other than designated areas where nudity is acceptable such as in nude beaches, unwelcome exposure of an adult's genitalia is the most common example of indecent exposure. More specific cases of indecent exposure may also involve masturbation, sexual intercourse, etc. in a public place.
