U.F.O. day

The one day during the menstrual cycle when you are in such pain that when you stand up, it actually feels like the uterus is falling out.

No, I can't go to aerobics tonight......I'm having a total U.F.O. day!

U.F.O.

the female equivalent of love handles. Caused by belly fat protruding over tight pants. Usually spotted in the summer when women wearing belly bearing shirts are common. So named because the fat sticks out and hovers around their tummies/hips, creating a shape quite like an unidentified flying object.

Whoa, check out that U.F.O.

U.F.O.

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.
