Catfish

A person that over eats. Their big mouth devours everything infront of them. After eating that excessive amount of food they are typically lethargic and have a swolen stomach and blank stare much like a catfish.

Bob- "Did you just see Jamie after she ate those two footlong philly cheese steaks and that large milkshake with extra whip cream!?"

Dan- "Yeah what a Catfish!!"
