I don't know how Will turned into Matt but whatever.
The point is that the one you're less close to of the two is the one who said all this. Mmmmmmkay.
Breaking it down:
Matt's a shallow jerk who pledged a group just because of the parties and status, not because he actually liked the brothers or bothered to figure out whether they actually liked him.
Nick's a pussy who can't do anything on his own, even when he's been given tons of encouragement to do so.
Consider yourself lucky that you are not stuck with either one.
