eatard
An eatard is a brainless dummy who thinks they're smart because they eat and talk nonsense.
"I got a 90% on that test. I'm not an eatard.", said the guy who flunked math.
"You're an eatard," I said. He just smiled and ate a whole pizza.
My friend's an eatard. He thinks he's a genius because he eats tacos and yells at the TV.
