F.a.b.s.
People who are so big they could be a wall, and they're always eating like they're going to die tomorrow.
My friend's dad is a F. A. B. S. He eats three burgers and still wants fries.
The F. A. B. S. in my class are always making noise and eating like it's a party.
At the restaurant, the F. A. B. S. ordered for the whole table and still wanted more.
