look up any word, like donkey punch:
Acronym for "Just For the Fuck"
Usually said when you tell your friends you'd do a girl and they disagree. Most likely cuz she's not very attractive, but ur a horny mothafucka and you'd her anyways.
Friends: "Dude, she's sort of ugly dont you think?"
You: "I dont care, I'd do her jftf"
