When someone fills their mouth with either beer, wine or some other alcoholic beverage to the point where their cheeks are swollen and then spit-squirt it at & into someones else's butt-hole from distance of no more than 6 inches away.
My buddies got a little drunk & carried away around the campfire the other night and one of them decided to poop without grabbing TP and had to ask the other to give him a festive douche in order to get right.
Weird thing is my other buddy told me how much HE enjoyed the night, but they are both married so I guess they aren't gay.
