Something that you say out loud when someone is bullshitting you, or when you simply don't believe what the fuck they're talking about. Beware, for the bullshitter (aka challenge-artist) may be sneaky about it by slightly tweaking the story/comment to increase their cool-meter. You may also throw out a red flag (like in the NFL) if you have one handy, at the moment that the bullshit is dropped on you. You will find that the same people are constantly "challenged", because they like to live lies, and they feel better about themselves by making up stories about something 'cool' that they did, or something 'cool' that happened to them.

a drinking game orgininated in the northeastern oregon town of milton-freewater. at any moment during a party if you've heard the word "challenge" shouted you must consume whatever you have in your hand as fast as possible. this is a good way to weed out the pussy drinkers who think they're rugged.

assists are also allowed
challenge: straight up

guy 1: dude that chick over there is hot.
guy 2: you should go over there and CHALLENGE!

challenge: with assist

guy 1: hey chuck, fill in the blank. i _______ you to a dual.
guy 2: is it by any chance, CHALLENGE!
