adultly 

The mash up of the word "adult" and "like" together mainly used by lazy people, because lets be honest, who got time to write out fully two whole words?

I didn't know whether I should cry or laugh at how "adultly" they were acting.

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.”

Adultler 

Like an Adulterer, but much worse. Someone who cheats on their spouse so much, they are akin to the Hitler of dating. It is rumoured that the original Adultler had as many as 6 million affairs in an event dubbed "The Hole-a-caust". Hole-a-Caust deniers say this is greatly exaggerated and that the actual number is likely much lower, perhaps 10 or 20.

"Well, duh... of course he cheated on you... he's a total Adultler"

"You sir, are worse than Hitler - you're an Adultler"
