What does it mean if a guy wants to grind on you?

Gyrating of the hips, specifically in the pubic area...or dry humping. Imitating the actions of sex, but still having all of your clothes on #2 answ: It means you should put some distance between you and the guy that could care less about your mind, peronality, or reputation. He's a loser. Let him 'grind' on some trashy 'ho. You're better than that putz.
