F.a.b.s.
People who are so big they could be a door, and they still manage to eat more.
My uncle is a F. A. B. S. He eats a whole pizza by himself and still wants dessert.
The F. A. B. S. in the cafeteria are the reason we have to clean up after lunch.
My friend's brother is a F. A. B. S. He eats like he's trying to win a eating contest.
