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 actually have to be fat or ugly, just less attractive than the people they are with

Also, a person can be one of the hottest in one group of friends, and the least hot (and therefore the Duff) in an other group

The duff is the less attractive friend and therefore easier to talk to than the hotter friend you are trying to score
