How to flirt with guys without looking stupid?

Well, there's this guy I like... but he's in a different clique. You know, the popular clique. I, however, am in the sort of upper-class unpopular, and I have a bunch of friends in his clique, i'm just not really friends with him. We're doing a science project together, so I have a lotta time with him, to just talk.... how do I flirt without being too obvious and stupid? Thanks for your help.How to flirt with guys without looking stupid?

';upper-class unpopular';





lol





EDIT: Sorry, that just made me laugh, anyway don't be super obvious you like him, just smile a lot and give him compliments, talk about stuff you both like *shrug*
Say ';hey, I really like you.';


Guys don't get hints. Trust me. They don't.
Just smile alot, compliment his hair, or his smell. Laugh at his jokes but dont over do that one. But most importantly, be yourself
I wouldn't nessecarily flirt. I mean talking in forms is considered flirting.
Intreeeesting.
