UFOS 

Noun: Pronounced "UF-Foes".

Acronym for "Unidentified Faction Orientation Syndrome"

When a group of cunts, jocks or sluts support the nameless guy that nobody knows at the back of the class with no friends so they look good infront of the other factions, that said nameless person gets "UFOS" and evolves into a Level 2 "Ufo". He then usually becomes part of the group.

Also, sometimes acronym-ed to "Unknown Fucking Organ Donor" because that's all they're good for really.

Slut: "Hey there honey, what's your name?"

Everyone else: "Holy shit, they got another one. He's an Ufo now."

Teacher: "Everyone please be nice to our new Student, Tom Yung."

Everyone: "Uh god, there's another kid with UFOS... Who's gonna snatch him first?"

ufo's 

The best pants in the world. The are light as a feather, they dry fast if you spill something on them, they don't wrinkle, they are easy to get in any size and are very adjustable, they come in almost every color, they have buttons on the pockets so your stuff doesn't fall out when you sit down, and they're the most comfortable pants ever. They fit snuggly around the waist and the legs are wide without looking like hakama pants (those dress-looking pants that you see martial artists wear sometimes)

I have four pairs of UFO's because they are the candy cigarettes of pants!
(you know, because candy cigarettes are the best candy ever)
