Fat Ugly Pig also Fucking Ugly Pig
1) Someone who has been cursed with both a lack of good looks as well as being over weight.
2) Someone who is so hideously ugly that looking at them makes your
eyes hurt.
"Beulah Balbricker" from Porkys and the "Momma" from Throw Momma From the Train are 2 famous
people/movie characters who were FUPs.
I wanted to poke my eyes out with a sharp and
hot object after seeing that FUP wearing a tiny bikini at the
beach.
