When a shart goes beyond conventional means. A solid clump of poo that is not recoverable by a clench of the buttocks requires a unique set of variables at play. The fart needs to have enough force to propel the fecal clump fast enough to escape the clench reaction of your standard shart.

An added variable, but not required, is that said fecal matter fall out of your pants all together, making you want to take a similar route off of a bridge or tall building.
