the female equivalent of love handles. So named because the fat sticks out and hovers around their tummies/hips, creating a shape quite like an unidentified flying object, and also results in the woman being classified as an Un-Fuckable Object. Thus, U.F.O. is an acronym for Un-Fuckable Object.
Wow. check out that U.F.O. She is on fat Biatch. I'd have to drink 3 40oz to go home with her. I'm sure she's got a nice personality though.
