One of the funniest and most disgusting videos on the internet. The legacy of this video has grown rather rapidly. The video involves 1 woman defecating into a cup while her and another woman proceed to lick and eat the feces. Later they go ahead and throw up into each other's mouths.
There are countless videos, mainly on youtube, that show reactions of people that are watching the video for the first time. I have personally tricked people into watching the video and I have to say, it gave me quite a laugh, and I think a couple of them are now scarred for life.
WARNING DO NOT WATCH THIS VIDEO IF YOU ARE QUEASY, BECAUSE YOU WILL PROBABLY THROW UP!
Me: Here man watch this video, it's called 2 girls 1 cup.

*Boy clicks the play button*

Boy: This is gonna be bad isn't it?

Boy: ...

Boy: What the... why is she shitting in a...

*Hilarity ensues*
