MegaRave 

An illegal event heavily promoted across the Internet (particularly SquatJuice) as being the biggest rave evar, to the point where Police forces can hardly open their web browser or newspaper without stumbling across a mention of it.

This forces their usually lazy hand into sending as many officers as they can find to break up the party with as much force as they can, creating a situation known as the MEGARIOT.
