What's a Shoey?

i've been to like a few crazy house parties in australia. Most of them have been in brighten, which is my hometown. There are some parties that are just like kind of like you know that scene from american pie where you see that scene and think there's no way thiscrazy shit's happening. i remember one time where there was this party who had heard from a friend who heard from another friend who hearing from another friend that there was a party happening in the middle of fucking nowhere. It started off with a chair so they get a chair out and set it all on fire then people start dancing around for some reason and its like caveman mode activates or something
