Methane and sulfur compounds

Methane and sulfur compounds are stuff that comes out of your butt. It's basically a fart. The methane is the loud part of the fart, while the sulfur compounds are the stinky part. The more sulfur compounds it has, the stinkier the fart.

Ew! Who let out methane and sulfur compounds? It stinks! Stinky fart!

methanical pancake swiveller

A man with long, greasy hair, green teeth, baggy pinstripe trousers with braces and white plimmies. He sneaks around on farmland waiting for a cow to drop a pat. Slavering with excitement he drops his pants and swivels his bare arse on the still-warm bovine pancake whilst making high-pitched mooing sounds.

Its amazing how many methanical pancake swivellers you see on a sunny day.

Farts that can often leave residue, often in the form of streaks, which can cause a wet muddy feeling between your ass cheeks.
