What it means is that you just get to ignore this person and that their words have no weight at all with you. Whatever his problem is,it has nothing to do with you, you're just the target or outlet for his issues.
I agree with two previous posters. He wants attention, and he has a crush on you. But chances are that he is too socially inept to initiative ordinary conversation like a normal person.
its his stupid way of getting your attention. next time he does it, smile at him and say "either you find guts to finally ask me out, or beat it". or just ask him out yourself.<br />
men aren't as brave as they lead on :)
He has some kind of mental issue that causes him to fixate on others. It sounds like you need to stay far away from him. If he makes any threats report it to campus and local police as well. Don't worry about why he hates you - just take it serious. Especially when there is no reason for it!
they want your attention
It means he has made a judgment about you ba<x>sed on what he has seen of you so far.
His problem? He doesn't like you.
Either he's jealous. Or he likes you and he's scared of showing it. :P
He's got a crush on you.
