Adultling 

One who is legally an adult (18 years of age) but is still learning how to adult i.e. regularly make and eat quality food, keep living spaces clean, and do everything that your mom either had to nag you to do or just did for you.

Adultlings in college often seek the advice of full-grown adults about how to function in a responsible manner so they can fully transition into adult-hood. An adultling might say “how do I adult,” or “I suck at adulting.”

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.
