Rotten Ripper
A particularly nasty smelling fart, expelled with considerable force and volume. Named due to the fact that it smells rotten, and the force of it coming out your ass feels like it is ripping your sphincter open.
Dave had eaten bean and cheese burritos for lunch, and when I rode the elevator with him at the end of the day he cut a "rotten ripper" so loud the elevator shook, and so nasty smelling I thought I would vomit.
