Dewlap

A fat person's double chin. Originates from a term used to describe "a pendulous fold of skin under the throat of a bovine animal"

I punched that fat ass right in his dewlap.

dewlap

1. Sloppy fat beer gut, as in "his belly do lap over his belt."

2. Loose skin hanging under the neck, especially of a cow.

She's so fat you gotta lift up her dewlap to find her snatch.
