Wavelength, For Playing at a Party

Given an axis (“Mysterious / Obvious”, for example) and a percentage along that axis (say 72%), come up with a single word or idea you can tell your friends such that they can guess the percentage given the axis. That’s the game: is “mentioning I have to call my mom because it’s my birthday” 72% obvious?

This game is fun at a party. It takes 30 seconds to learn, and everybody gets to debate exactly what percent hipster they think James Franco is.
