fartbutt

A combination of the words "fart" and "butt", showing immaturity through a lack of a better insult.

"Go buttfart out your fartbutt, butt farter!"

Fartbutter 

Fartbutter is a fart let out with a little wetness that stays in between the buttcheeks. It makes your buttcheeks slipper, so they slide back and forth as you walk or even run. So as the old saying goes "slippery when wet"

Damn, my ass has enough fartbutter build up in it.

Geesh, when will I let a fart with out the butter?
