When a chick lays on her back with the down spout from the house inserted in her pussy. 3 guys get on the roof. 1st guy pukes down the spout, 2nd guy takes a shit down it & the 3rd guy takes a piss to wash it all down.

When you are so drunk that you are killing everyones high or buzz and therefore must be choked out with a pillow or some form of abnormal weapon.
When you are at that party and that annoying girl in your history class, who you thought was straightedge, comes up to you and pulls a Dirty Down Syndrome which then forces you to strangle her with a giant crayon.

Kind of cousin of the Dirty Sanchez. Here, while banging a girl from behind, stick a finger up her ass and get some poo on your fingertip. Then put a little on another finger on your other hand. Right when you cum, rub a finger under each of her eyes, giving the appearance of an athelete's eyeblack, and then yell "First Down" and make the hand motion a football ref makes for a first down.
