Nudity
In different counties and localities, public nudity is a matter of common understanding of proper behavior. More often, prohibitions regarding exposing the body are written into law. The basic prohibition is outlawing exposure of the genitals in public except where it is specifically allowed. The violation is often called indecent exposure or public indecency. Public exposure of breasts, or specifically the nipples, is often included in the legal definition. Most violations are considered minor, but may be serious crimes when there is intent to cause distress or harm to the person viewing the nudity. Serious crime is assumed when the target of the exposure is a child. Intent is difficult to establish, but is assumed when a single individual exposes their genitals suddenly to strangers in a public place. This is often called "flashing". Such exposure may be a sign of exhibitionism, a mental disorder marked by feelings of pleasure in exposing oneself.
