1. Unidentified Flying Object. Usually refers to an alien spaceship that we don't know anything about it
2. Ugly Fat Old. Usually describes women who are well past their days, and even then they probably weren't very hot. They are usually seen in public in twos or threes and the only thing they do is talk to each other no matter the circumstances.

Unidentified Flying Object. Has evolved from a simple military classification to a word synonomous with aliens, Roswell, conspiracy theories, and general paranormal nuts.

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)
