look up any word, like boo:
1) A term of endearment used to address/describe a woman possessing a FUP.

2) The physical presentation of the FUP as it billows out and over a pair of constricting jeans or stretch pants. It's just like a muffin top, only sweeter.
1) "Hey, FUPcake. Do you want to go to KFC later?"

2) "Those new leather pants make you look like total FUPcake, mom."
