What occurs at a drinking party when everyone drinks so fucking much that they all pass out and fall on the floor and/or on top of each other.
Last night's Roman orgy of a slumber party ended when everybody(guy and girl, clothed and naked) passed out on top of each other in a mass alcoholocaust.

Then the next morning when I woke up and while everybody was getting dressed and leaving, I found out that my face got all bloody when one of the cheese hog bitches fell on top of my face, breaking my nose!
