It ain't your booty, it's yo beauty 

This is usually said by a guy to a girl, but it could be used vice-versa. The guys is trying to tell the girl that he appreciates her not just physically, but also her overall beauty as a person.

Is the guy being honest? That's up to the girl to decide.

Guy: Hey girl, can I get your number?
Girl: I hardly even know you, we just met here at this club.
Guy: Yeah I know what happened. I'm not as drunk as I might seem...listen, I'd like to get to know you better.
Girl: Get to know me better in what way?!
Guy: No, no don't get it twisted! It ain't your booty, it's yo beauty.
