Watching other people watch the most disgusting video of all time.

In the opening sentence of his landmark study The Anatomy of Disgust, law professor William Miller addresses the difficulty presented by his subject: "Disgust raises special problems that closely related topics such as, say, sex do not." Later, he elaborates with a quote from another scholar: "[C]ontact with the disgusting makes one disgusting. To study disgust is to risk contamination; jokes about his or her unwholesomeness soon greet the disgust researcher."

Disgust, it seems, is hard to investigate without being mocked or without becoming disgusting yourself. With those caveats in mind, let's turn to the phenomenon of 2 Girls 1 Cup. Immediately we run into trouble: 2 Girls 1 Cup is a video that's too disgusting to write about. In order to discuss (and perhaps learn from) 2 Girls 1 Cup, then, we must study the faces of those who have seen it.
