I guess it was bound to happen. Male Underwear Manufacturers Aussiebum and Andrew Christian appear to be going Head-To-Head (or is it Dick-To-Ass) in competition for the gay male underwear market. Aussiebum has just released it's athletic brief/jock line appropriately called Riot that copies Andrew Christian's propensity to highlight and frame the well-toned butt. Aussiebum's products are usually better made than AC's and last longer but they come with a higher price tag. May the best butt enhancer win!
