The name of a very good looking guy, who will always be there for his friends, but once you fall for him he'll act like nothing ever happened. He won't give you a straight answer, even if he does like you back. He's a total chick magnet, but a horrible flirter. Once he gets a girlfriend, he starts acting a little different towards his best girl friend, because he cares about his new relationship too much to risk jealousy. But none the less, he's a truly amazing guy, that you know will always be there for you through thick or thin.
"See Zack over there? Yeah, hes got the ladies all over him. Even his best girl likes him. He's acting like SUCH a Collin."
