my flab

A response given to a movie theatre ticket collector when they ask you what that bulge in your sweater/jacket. What it really is is candy/food that the user purchased prior to entering the theatre to avoid stupidly high consession prices.

Cinema employee: "Ticket please, theatre 1, first on your left. Ohh, excuse me sirr! What is that bulge hanging behind you."

person: "my flab"

Cinema employee: "Oh, very well then, carry on"
