It's hard to make out, but that amorphous blue thing is supposed to be a wildcat, which is the UNH men's hockey team's mascot. Thanks to some lewd UMaine fans who attended last Friday's game between the two schools, that poor wildcat has a big dick in its mouth.
According to the Bangor Daily News, the sign was confiscated right after the game started, so nobody in attendance had to spend too much time contemplating if making a wildcat suck a dick is even a good burn, a thing I am doing right this very moment. I mean, the wildcat would just bite that dick in half, wouldn't it?
