It means he thinks you have a nice butt but doesn't like you.
It's a good thing. It means you have a nice, athletic ass that doesn't sag or look gross.
It means that you are a nice person.
BOO!
There is a fine line to whether he likes you or your butt :)
it means that he likes you and he thinks your nice
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).
it means that he's hitting on you and wants to get to know your boobs LOL i no cuz i am a guy hope you have a nice butt
He's being polite; it doesn't mean anything.
well, that means that he is trying to be nice and do something that you like
It means you have no boobs :( And it means that he is not a very nice person.
