As an insult: "Eat my fromundercheese you unhuman fiend"
A swift joke amongst friends at a dinner party:
Jill:"Would you care for some fromundercheese with your biscuits and wine"
Party: "Oh... ha ha ha ha"
Me: Ight bitch. Lick the From-Under Cheese off while you're at it.
Joe was beating off for 2 straight hours and had a load of From-Under Cheese under there.
Eminem (Crack a Bottle): Kiss my butt, lick From-Under Cheese from under my nuts.
