It means that he is a very bad choice for a boyfriend or even a friend. He's after you for sex, not love. If someone tells you you have an 8-Ball butt, then that's what he's interested in, not your feelings, not your personality, not love. He just wants anal sex.
*The colloquial meaning of "8-Ball butt" is more or less "An anus that is fun to play with."
It means he thinks you have a nice butt but doesn't like you.
There is a fine line to whether he likes you or your butt :)
Ewww! here's what i suggest: slap them on the face and say their butt is hard. see how they like it.
That he has no respect for you or sense of humor (if he thinks he is being funny).
he is most likely, A. hitting on you B. trying to seduce you or C. just likes your butt size.
This is a rude and inappropiate way of saying he likes your rear end.
that means you have a big bahdonkadonk and he likes it!
It's a good thing. It means you have a nice, athletic ass that doesn't sag or look gross.
It probably means the guy likes looking at the girl's butt.
means he wants to go out with you
They probably like them!<3
Retard, Wasteing peoples time.
