Somethings on them or he likes them and wants to kiss them.
He might be thinking about how it will feel if he kiss you.
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!
It's either open or he wants you.
There just looking into the other person with love not thinking at all.
either he finds you attractive, wants to kiss you, is mentally ill, or wants the snack in your lunchbox.
