Collin

A stuck up jerk. Thinks he's cool, he's not. Unless he's a girl, then that's a pretty messed up name for a girl. Collin's are usually blond and obnoxious. Watch out or you're guaranteed a headache worth a lifetime.

"Can't he just shut up?"
"Probably not, I think he's a Collin"

Collin

Collin or Colin

Collin is that guy that looks nice but is quite deceiving. You can never be sure what his reaction will be or how he will treat you. When dating a Collin be careful because he will show his good side only to result in breaking your heart.

Girlfriend: Collin is so sweet!

Friend of her: are you kindling! He is so mean! Did you hear what he called girl3!!?!!

Girlfriend: now really he is so nice.

Friend of her: you only think that because you are dating him! Just a while ago before you were dating you thought he was a dick!
