To shit and urinate and jizz on a tarp and then throw someone in the middle and roll them up in it and roll them down a hill.

A room full of people drinking fucking sucking pissing shitting spitting licking eating. To protect the house a tarp is laid down. Hence "a tarp party"
That wild hippy woman just pissed on me from across the room, so thank god its a tarp party!
