What does it mean if your crush comments on your butt?

So my friends and my crush were talking and we were making fun of the distance guys (We are the distance girls) and all of the sudden my crush said "Lets make fun of the distance girls... like for instance Katherine (thats me) she's the only one that has an ass"... could he like me or just my butt?
