HEY DUDEa u heard of corey in australia, he did that and 500 people turned up and it was destory time, you pray its not you and someone doesnt die in your family home , ok
Something like that happened when I was celebrating my 17th birthday, about 300 hundred people showed up! Pure chaos, they wrecked the whole place! Some people even managed to get their footprints on the ceiling (but that wasn't the worst by far)... don't ask me how the hell they did that.
I had to stop the mayhem in the middle of the night because of a massive brawl inside and then they continued outside because I refused to give away any more booze.
Best thing: they had to burn the place down at the easter fire a few weeks after because it was completely wrecked!
