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.
1.) A person that obsessively eats and steals your food.
2.) A name you call someone when they're being mean, rude, or annoying. You may call them this when they eat too much or don't feel like getting off the couch.
She steals my food everyday..She's such a fatwad.
I ate too much for breakfast.. I feel like such a fatwad.
Get away from me, FATWAD!
