Nasty Fest 

Noun: The most disgusting, vile, obscene display of total drunkenness, loss of morals and values, idioticy, and desecration of all things holy and politically correct. Nasty Fest is to other parties as the atom bomb was to thousands of Japanese civilians.

Some friends of mine held their annual Nasty Fest, and by God you should have seen some of the stuff that went on there. Things that would have made grandma's cry. It was so awesome.
