Methane Exchange

When you are eating a girls ass out and she farts in your mouth. You then hold the fart in your mouth and pass it from your mouth to hers.

"Man last night this chick and I were fucking, but she farted in my mouth when I ate her ass out"
"Did you swallow it?"
"Nah, man I just did a methane exchange and gave it back to her."
"Nice, dude"

Mechanic’s Special

A bullshit term car sellers say when they’re trying to scam someone by selling them their trashed car instead of sending it to the scrapyard.

Buyer: *Searching for cars on OfferUp*

Seller’s ad: MECHANIC’S SPECIAL!!! 2020 Mustang for sale, engine and transmission are completely blown. It was also in a high speed collision

Mechanism Male

A Mechanism Male is defined as someone, usually male, who uses the mechanisms of the world to their own gain. Such as using the mechanism of trust to become filthy rich in the subtropical islands.

Take that guy over there as an example, what makes me different from him? He’s bigger than me, and he looks like a good student. He probably gets a big allowance from his parents, too. But he gets bullied. Meanwhile, I get money and sleep with women. Because he’s a beta cuck, and I’m a mechanism male

Mechanix

A sweet song by Megadeth, written by Dave Mustaine when he was still in Metallica, they took it and changed it to four horseman. Mustaine responded by making it really fuckin' fast and putting it on Megadeth's debut album killing is my business, which is also amazing. It is about working in a garage and fucking a female customer.

"make my drive shaft crank, make my pistons bulge, make my ball bearing melt from the heat." Lyrics to mechanix
