Jabbese, or Jabbesity
A person so fat, they could be a new kind of planet. Jabba the Hutt was the first one, and he looked like he could swallow a spaceship.
My brother is a jabbese. He eats so much, he could be a walking buffet.
That guy at the gym is a jabbese. He looks like he just won the snack lottery.
My friend is a jabbese. He eats so much, he could be a food group.
