An uncontrolable urge to spout profanity in as many languages that come to mind in a whole body expression of angst where you don't care who's in the room and people often ask to be warned if one starts foaming at the mouth.
A gimmick by Adult Swim and adultswim.com to get 1 million hits on their website, which actually worked. It was set up like this- Adult Swim puts an "employee" in a chicken costume and hockeygear under their webcam and promote the shit out of it not only on the block of shows (that I watch nightly and recommend to anyone who likes cartoons for a more mature demographic, and the anime..., though the anime is chopped and not fully in it's created format) and at comic-con. Within a week, 1 million people visited and watched hockey chicken, causing him to be "freed" off the webcam. Well played, adult swim, well played...
FREE HOCKEY CHICKEN!!! DON'T LET ATHF END!!! FUCK SEALAB!!!
...if you've watched adult swim for a while and are a big fan of aqua teen hunger force you would know what I was talking about up there
