One arrives at a party and finds the situation bad, uncool, boring, lame and/or gay. One would describe the party as a "shitfest". Normally used in context as such, "What a shitfest!"

When 2 groups of people get together (for most likely bowling - 5 pin) and get shitty. It's like woodstock except with shit.
