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!

methane lab 

An extremely stinky bathroom- one that smells like an overflowing septic tank is right underneath it. Meth labs generally have several stalls, each of which is equally noxious.

I'll be right back I have to go make a deposit in the methane lab.
The meth lab in the videotpae department where I work smells like its overflowing with 60 years of shit.

methane freebie 

A coolidiculous and/or offensive term for a very public, very powerful and very smelly fart.

Shame on you if you know how to release a methane freebie in public, especially at the dinner table.

Methane Cuddle 

While spooning (a form of cuddling), the little spoon farts into the crotch of the big spoon, warming them both.

On cold winter nights, Methane Cuddles help me sleep.
