The Colostomizer is a particularly sexy motherfucker, specifically with respect to his relative skill at any of a number of competitive endeavors. Whether it be videogames, sports, or pissing contests, The Colostomizer will fuck you up so badly that, once he's done with you, you'll be in desperate need of a colostomy bag (read: your asshole will be loose to the point that you can no longer control when you take a shit).
Jesus H. Christ, The Colostomizer just skullfucked you through your asshole! How does it feel to get sodomized by a freight train?
