What does it mean when a boy stares at a girls butt and then stare at her lips?

As a guy, i admit i do this. When a guy stares at a girls butt, it means he is attracted to you. When he stares at your lips, he is hinting that he wants to kiss. I don't know if you are in a relationship with this guy, but if you are, take the risk when he stares at your lips and kiss him! Guys make the first move a lot, but they love it when the girl does!
