U.F.O.

The sexual act in which a man performs on a woman (preferably someone's mother). First all the lights are turned off for total darkness. Next the man slips a glow-in-the-dark condom over his penis and then begins to float around the dark room ; thus giving the effect of a flying spaceship, or other un-identifided floating object. The woman then is invited to catch such object with whatever she pleases, i.e. her mouth or other orifaces. When the man grows weary of floating around, he then proceeds to crash-land his "ship" into the woman's "Area51" .

"Hey Mitch, I totally U.F.O. 'd your mom last night ! "

"She always loves when I crash my U.F.O. in her. "

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.
