lewd and lascivious

lewd and lascivious adj., adv. references to conduct which includes people living together who are known not to be married, entertainment which aims at arousing the libido or primarily sexual sensation, open solicitation for prostitution, or indecent exposure of genitalia (which is itself a crime). Due to the tendency of judges to be overly careful in writing about moral and/or sexual matters the definitions have been cloaked in old-fashioned modesty. Today the term usually applies to pornography, prostitution, and indecent acts. (See: pornography, prostitution, indecent exposure)
