F.U.F.S.
Meaning: Fucked Up Father Shit. Usually used for a girl who is damaged emotionally because her father either abandonded or abused her. She will either act slutty, needy, desperate, or stand-offish. This kind of girl isn't always easy to classify as a F.U.F.S. But she's definitely hurt.
"Man, that girl is so an F.U.F.S. Steer clear of her!"
