The orange dust that coats your fingers and lips after eating Cheetos. This is why you shouldn't eat Cheetos in public unless you have a wet-nap handy.
"I know you've been eating my Cheetos again - You've got Cheet all over your clothes!"
"Shut up" in a ridiculous manner. Usually telling someone who has said something idiotic, and therefore matching their
idiocy with "Cheet Epp!"
Sometimes said numerous times getting louder and louder and more and more annoying/ridiculous. Thus warning the victim to stop their banter and get a brain.
Idiot Girl 1: OMG Garlic Aioli is like, MY LIFE. I couldn't live without it. It's actuallymy life!
Logical Bystander: CHEET EPP!!!
