The stuff left on the bottom of your weed bags. All the stems, crystals, and leafs. Often used as a cheaper alternative to buds in baking. Though often mistaken as good, and used in joints and bowls. Known to be sold for as cheap as 30-40 dollars an ounce.

Get the duffmug. by SauceMilliken July 31, 2017
Get the Duffmug. 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.
