duff

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.

Hey bro, got any of that duff? I need to make another's batch of weed brownies.

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
