Sherdog is one of the biggest MMA website, therefore has a forum with high amount of members.

The moderators of the forum are most likely the biggest cocksucking faggots in the history of the internet.

These douchebags actually think that hold a position of power over a bunch of morons who kiss their ass because they are afraid of the ban hammer, thanks to their worthless and ridiculously high post count.

Sherdog poster:" BJ penn is a whining faggot"
positivebalance (greastest sherdog forum moderator ever): "fuck you motherfucker! don't diss my husband! arghhhhhhhhhhhh!" (*strikes teh ban hammer*)
