A very painful insult to inflict on someone. If someone calls you a buttass you know your a loser with no friends.
by Asmith32 January 22, 2007

A name to explain what a stinky person's room smells like, or even how to explain how the person smells. (perhaps someone who wears no deoderant) Even sometimes used to explain a pig or donkey's stench.
Actual Example with dif. names:
Chris: EWW! it smells like buttass in here! where's the Lysol????!!?!?!
Bob: In the bathroom!!!
Chris: EWW! it smells like buttass in here! where's the Lysol????!!?!?!

Someone who would be dumber than the ass of a butt, but since an butt can't have an ass, the person who is buttass stupid is in fact the biggest idiot alive.
