Raver Plague
After attending a all night rave it is common that a lot of people will get sick. This is due to the large amount of people inside of the venue and since it's warm germs stay airborne longer. People also share water bottles a lot which spreads bugs or virus faster. Due to the lack of sleep and people doing drugs or drinking excessivly the immune system is not quite up to par.
I've caught the raver plague.
