When you're out riding/hiking/climbing and you drink so much on the trail that you and some/all of your buddies have to bivy on the trail in a tent or bivy-sack that is not rated for the number of occupants using it, all of whoom are male and intoxicated.
We got so loaded on the trail that we had to camp out, but J.R. had forgotten his bag, so he asked if he could BivyWack with someone.
