adultager 

college-age kids who aren't yet mentally capable of making adult decisions. Similar to the usage of the word "tween" to refer to pre-teens.

That boy is the typical adultager... always broke and asking his parents for money; always has an excuse for his poor behavior; never gets his shit turned in on time without someone holding his hand; doesn't know how to take care of his own business.

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.
