crush; A guy/girl that you are crushing on, but you don't want to like that person. So you want to have the fub ended right away.
Tyson is Tori's fub, but he is a preppy jock who is an A**-hole.

Fat Ugly Bitch also Fucking Ugly Bitch

1) A woman who hit the trifecta by being an asshole,
ugly and overweight.

2) A woman who is both an asshole and
who is so fucking hideously ugly that
looking at her makes your eyes hurt.
Roseanne and Rosie O'Donnell are unattractive
fat women who are also known to be real assholes.
They're the inspiration to FUBs everywhere that they
too can be fat, ugly, act like bitches, treat guys
like crap and yet still get rich and famous...
Thanks for nothing you FUBs!

I wanted to poke my eyes out with a
sharp and hot object after seeing that
FUB staring out at me from my office

Acronym: Fuck You Bitch

Secretary: Lee-ah, is that how you say your name?

A state of absolute nothingness where you have no idea what you are doing with your life, you don't know what to think, and you don't even know how to function properly anymore. This is especially bad if your name is Deborah.

Deborah's friend: "Sucks to suck, Debs."
