A ridiculously fat and smelly person. Prefers wearing mullets but becomes greatly offended if the mullet is insulted. For good behavior, reward with shampoo and deodorant. Toilet Paper makes a great reward substitute. It is rumored that a fatwad has three buttholes but this fact hasn't been proven due to a lack of volunteers willing to get within thirty feet of a fatwads ass.
Person 1: Dude, is the fat wad here yet?
Person 2: Yeah the smell wafted past about five minutes ago.
