Boosh

Once upon a time there was a terrible, terrible game called Haze. It was hyped beyond control as a spiritual successor to Goldeneye/Perfect Dark/Timesplitters (all Good Dudes favorites) as it was being made by a splinter group of Rare called Free Radical.

The game was purchased and we quickly found that it sucked. However, where it went awry in terms of game play, the dialogue was so over-the-top it was instantly quotable.

Many of the main characters would hype themselves up by yelling "BOOSH!" at the top of their lungs before taking a bunch of drugs to help kill people better

Now, you may hear Good Dudes use the same exclamation as common parlance."'BOOSH!'"
