A term that was popular in the early 2000's and is an acronym for "designated ugly fat friend." In modern day, this term is only used by douches who can't keep up with current slang, and by stupid ass middle schoolers who think they are the shit because of the 2015 movie of the same title that attempted to resurrect the term and make it "cool."
Stupid Person 1: Why is that ugly bitch hanging out with those hot girls?
Stupid Person 2: She must be the DUFF.

Designated Ugly Fat Friend
The DUFF isn't always ugly or fat, the DUFF is the least attractive friend ( They can still be pretty but not as pretty as the friends) in the group which makes the others look more attractive. The DUFF is the approachable friend in the group who gives intel about the more attractive friends.

Designated Ugly Fat Friend
Doesn't necessarily have to be fat, or ugly, but is less attractive than the friends she/he hangs out with. Men/woman usually befriend a duff to get closer to his/her friends. A duff mainly gets used for info and or help, and is often lead on mistakenly or purposely. Do not allow the duff to realize who he/she is and why you are using them, because you will 100% lose them as a friend. If you even care.
