Someone who doesn't join a fraternity for some reason. Maybe they're a douchebag who shouldn't join in the first place, or maybe they're balled for some reason. Regardless, they are not fraternity material.
"I don't wanna join a frat because they are gay," said one GDI. "Well, I guess you wouldn't fit in to my fraternity anyway. We don't refer to our brotherhood as a frat. Would you refer to your country as a cunt? If you would, get the fuck out of my house. If I see you again, I'll haze your ass so quick I won't even be able to 'ball your ass."
