adultery 

Adultery is behaving like an adult in a primal sense.

Some consider adultery as a potentially dishonest sexual act, and use verbs such as commit. ie She committed adultery. Some consider adultery in the same sense as a greeting or a handshake, and simply behaving like an adult. Hence the word ADULTery.
