In reference to the skiing and snowboarding industry, UFO stands for uncoordinated fucking orient. Applies to all the asian, indian etc. punters who cant ski or board worth a damn and will never be able to - why? Because they are a UFO.

Abbreviation for "Unidentified Flying Object". The USAF defines a UFO as: Anything that relates to any airborne object which by performance, aerodynamic characteristics, or unusual features does not conform to any presently known aircraft or missile type, or which cannot be identified as a familiar object. (USAF Regulation 200-2)
The Mutual UFO Network (MUFON) is the world's largest civilian UFO scientific reseach organization.

Unidentified Flying Object. Has evolved from a simple military classification to a word synonomous with aliens, Roswell, conspiracy theories, and general paranormal nuts.
It's a UFO! Oh, wait, it's an airplane. Or a pie plate. Or a crazy person.

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)

UFO - Undercover Flirting Operation - a moment when two people who have no apparent public history with each other, exchange glances, smiles, suggestive looks, and other non-verbal cues, signifying that they indeed have some history. Often accompanied by restrained giggling, adrenaline rushes, and loud, double-entendre conversations with others nearby to "communicate" without directly talking to the person of interest. Also, referred to as a "Romeo & Juliet" or a "bump". Most often used by cheating spouses, inter-office romances, teens from different social standings (band fag and cheerleader), and in grade school children (often expressed in violent terms - pushing, pulling hair, name calling, de-panting, etc.) Very difficult to see, despite often being in plain sight.
Billy Bob: Hey Sally May, did you just see that? I think I just saw a UFO!

Sally May: where?

Billy Bob: That guy at the desk and that chick with her boyfriend keep looking at each other, smiling, and mouthing words to each other! Oh Wait, did you just see that! He just texted her, and then she checked her phone and smiled back at him! Well I'll be, it IS a UFO! Hot dog, Sally May, that's a once in a lifetime thing! Sally?

Sally May: Oh sorry, I was just checking my phone, I just got a text from a friend. Nothing important. what were you saying?
