Usually occurring at house parties, a situation in which there exists a huge imbalance between males and females. In which there are 10x more single males at the party looking to get laid then there are available females. A cock festival can also be declared when there are loads of females but they either have b/f's or are Christian nut jobs..in which either cause you're not getting laid.

An illness which inevitably sets in when one returns home from attending a music festival.

Causes include:
-Between 2 and 10 hours sleep over a five day period.
-Living in your own dirt.
-Shouting and screaming a lot.
-Excessive consumption of both legal and illegal substances.
-Being too tight to buy food and hence going without for five days.
-Dehydration.

Unfortunately, due to the self-inflicted nature of this illness little sympathy can be expected.

When a female is at an outdoor music festival for 6+ hours and her vagina turns into a musty, sweaty, swampy mess
