when you fart into a casserole and place the casserole in a conspicuous place so that the next person to open it and smell the wonderful cooking will smell ones ass instead. one may choose to place the ass-casserole in the fridge, oven or countertop. a truly marvelous practical joke that will provide hours of family fun and laughter. feel free to use this gag at family dinners, reunions, pot-lucks, parties, funerals or any occasion.
ooohhh, whats in the casserole? lets see... oh, oh shit, oh thats just wrong, who would do that, why would you fast in a casserole?

- hahaha you just got a whiff of my ass-er-hole!
