U.U.F.O.

Album by Camellia and another version of the Unknown Flying Object (aka. UFO) that's more advanced, greater version with better technology, probably better than the invention of the Paradise Ship from Kirby's Return To Dreamland, or the Haltmann Company's UFO in Kirby Planet Robobot, used to take over all of Planet Popstar.

The U.U.F.O is known as the "Mystery Circle Ultra" or "Ultra Unknown Flying Object", according to the 1st album song by Camellia with the name “Mystery Circle Ultra / U.U.F.O”.

As mentioned before, it is predicted to be a more advanced version of the average UFO, explaining the name UUFO.

(DEFINITION IS FOR THE ACTUAL OBJECT THAT HAS YET TO EXIST OR BE PROVEN TO EXIST)

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.
