GFU

Get Fucked Undies: the kind of underwear that are often uncomfortable and may ride up, but make your butt look extremely good causing anyone to want to fuck you.

girl one: Eric is coming over tonight, I'm gonna wear my new GFU.

girl two: Lace boyshorts or thongs?

girl one: boyshorts.

girl two: Nice! They're so uncomfortable, good thing they won't be on long!
