Grumpy Muffler

The act of defecating into one's Air Duct or AC System, causing a foul shit-like smell within the entire facility.

My Boss fired me and I got back at his Bitch Ass by giving the office a "Grumpy Muffler", that'll teach them!!

amazonian muffler

When two vigorous women are frantically siscoring this action results in aeronautical exploration and finally, climaxing sexual transcendence.

Cajun muffler

When someone is plugged up and decides to drop the plug out and release the pressure it only leads to a cascade of shit flowing down their leg in JNKO jeans. Then using the bottom of the jeans as a mop just to spread it all over the floor like a rumba that ran over dog shit.

I thought it was a quick fart but turned out it was a cajun muffler situation.

Muff Muffler

Worn by women who are embarrassed about queefing in public.

I couldn't stop queering so I bought a muff muffler so that no one could hear it.

Boston Muffler

When you're penetrating someone anally and they fart, creating a muffler sound.

Brian "Did you go give it the chick you met at the bar last night"

Tony "Yeah, I gave it to her from behind. She even gave me a Boston Muffler. The vibration was amazing"

Mississippi Muffler Shredder

The act in which a hillbilly from Mississippi steals a hot muffler from his neighbor’s running car and uses it to violently circumcise himself.

I think Bill pulled a Mississippi Muffler Shredder instead of going to a regular doctor.
