2 Girls 1 Cup
2 Girls 1 Cup didn't originate on the Internet. It was simply the trailer for a pornographic movie. But when that trailer hit the Net in 2007, it became a sensation with people posting videos of other people's reactions to the disgusting clip of two girls defecating, eating excrement, and vomiting. The video was so nasty, porn legend Ron Jeremy couldn't sit through the entire one-minute trailer.
