F.U.F.S.
A girl whose dad messed her up. Now she acts like a slut, needs everything, or just ignores you. She's got baggage and it shows.
He said, "She’s a F. U. F. S. because her dad left her for a hot mom."
She’s a F. U. F. S. I know it because she texts me at 2 a. m. and cries about her dad.
I called her a F. U. F. S. and she said, "You’re one too!"
