percolation

Colloquial. The process whereby intestinal churning and tumult cause gases trapped in the digestive tract to become infused with particulate fecal matter, resulting in dense, suffocating flatulence capable of leaving a residue.

Despite the elimination of coffee from the menu, percolation remains commonplace at Taco Bell.
