Get the two girls one cup mug.
A scat video circulating the internet, which starts off as a generic 'girl on girl' video and then transcends to one girl defecating in a glass, and the other eating some of it, then sharing the rest between them. After this, one begins vomiting into the glass with the other eating some of the vomit. They then begin vomiting into each others mouths.

There have been many videos making fun of this video, "Two girls one cup REACTION". Many people find the video deeply disturbing and say it should be banned. Most of these people, however, do not realise that there are things such as fetishes and taboos which have many supporters and fans.

CAUTION: To those wishing to view the video. It is perhaps not for the weak stomached!

Guy: I s'pose...

The act of two women saving up their feces for an entire month, as the feces reach the peak of methane production they climb in and begin an act so vile. The two women begin taking clumps of feces and inserting it into their rectums, vaginas, and mouths. While this is going on a Mandingo party is raging on while a gentleman whispers in the womens' ears, "Better out and in, I always say."
My mandingo party was asked to help in a Two Girls, One Swamp party. It was a little smelly.
