No ordinary faggot, this faggot has exceptional abilities. Often found in forums or Call of Duty Multiplayer matches. Can be considered an antonym to Dragonborn, but instead of being an awesome dragon-slaying machine, the only thing he slays is fun. Often mocks you over the mic using retard noises, his high pitched voice (can be referred to as Faggot tongue), or really bad, juvenile "burns". If met IRL, he will appear as a normal child, but beware, he is born with the soul of the mightiest of faggots.
