An acronym for Designated Ugly Friend. Every hot girl has a DUF simply to make her look that much hotter. This strategy also works for average looking girls.

 Get the DUFmug.
Get the DUFmug. Dufful: A dramatic-ish person, who thinks she's Hilary Duff. The "dufful" people usually are drama queens/kings, cry all the time and get lucky out of bad situtations. Dufful Bitches are self-explaining. Dramatic bitches.

Get the duffulmug. Duffed (v) - The act of getting used and or manipulated by an attractive, mentally unstable person of the opposite sex.  Unfortunately this includes an abundance of flirting, profound mixed messages, and sexual enuendos that don't actually lead to SEX, merely the illusion that it will. The Duff usually ends by the Duff-er getting back together with their original girl/boyfriend, leaving the duff-ee with a killer case of blue balls/dry-gina.
