reverse appalachian farmer
A highly risque maneuver that requires three things. A man, a woman, and drugs. While taking various hallucinogens the man must insert himself into the woman (who is also taking hallucinogens). The man and woman must then roll down a rocky surface while still having sex, and additionally must engage in an intense philosophical debate. Smoking a joint afterwards is a must. No one has yet figured out exactly why it is called the reverse Appalachian farmer. The commonly accepted origin is these were simply the first people to do it.
