Lewdness

Behavior that is deemed morally impure or unacceptable in a sexual sense; open and public indecency tending to corrupt the morals of the community; gross or wanton indecency in sexual relations.

An important element of lewdness is openness. Lewdness is sometimes used interchangeably with licentiousness or lasciviousness, which both relate to debauchery and moral turpitude. It is a specific offense in certain state statutes and is included in general provisions in others.
