An obscenity is any utterance or act that strongly offends the prevalent morality of the time. It is derived from the Latin obscēnus, obscaenus, "boding ill; disgusting; indecent", of uncertain etymology. The word can be used to indicate a strong moral repugnance, in expressions such as "obscene profits" or "the obscenity of war". As a legal term, it usually refers to graphic depictions of people engaged in sexual and excretory activity.
