(n.) The Pariah's X occurs when two
people stand back to back and
fart toward one another, essentially farting on the other's
fart. As this happens, the two gusts intersect diagonally down forming the "Pariah's X."
The point of intersection, commonly referred to as "the danger zone," is the crux of the Pariah's X. Equidistant from both anuses, it becomes the joining force of the two farts.
