orange duffe

When you have to take a dump right after eating a huge bag of cheetos. Doritos and other orange texturized flavored chips do not count. You should only use the term when the situation is cheetos, not anything else. Spelling doesnt matter as long as its used in the correct context.

After you eat a big bag of cheetos you tell your buddy that youl just be a second, you go the bathroom and realize this might take a while that was a realy big bag of cheetos. For the first time ever youve come to the conclusion you have reached your limit and take a huge dump, the result... an orange duffe.

DUFF

(Designated Ugly Fat Friend) A DUFF doesn't always have to be fat or ugly, sometimes a DUFF can be cute, but they're there to make the rest of the group look better and to be the approachable one for anyone seeking inside info.

Man 1: "Hey do you know if that hot girl is single?"
Man 2: "I don't know, go ask her DUFF"

Duff

That place on the human body (particularly the female body) where the body makes contact when sitting-down, i.e. the erogenous area of the butt.

I'll bet her duff is as sweet as candy!
