fadshion (n.)

1. a fashion statement or trend that lasts for less than a week but then is considered completely geeky and out of style for the next few weeks, but will probably come back in a few years as a big hit again. This way, the people who keep up with the trends will end up buying the item of fashion, burning it after it turns geeky, then paying twice as much for the same thing in a few years when it goes back in style.
