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!!

muffler masters

The gayest group of men you’ve ever met. Until the clothes come off. Then suddenly everyone goes back to being hetero. Very strange

You ever been to muffler masters? So weird

Muffler

I also have a story that kind of applies and I think it with help you understand why I'm so antagonistic towards the thing you're doing here.

Iam "Ok, so... I had this car, right? And one day my muffler snapped off as I bottomed out in the driveway of a gas station. Mufflers on the ground. And not just the muffler but the entire length of pipe that stems from the engine to the muffler. I'm freaking out. I pick it up and try to stuff it into my car. The car is a small 4 door sedan. Only 60% of the muffler fits into the car. There's no way I can drive all the way across town without getting pulled over with half of a muffler pipe hanging out of my car. Some guy walks up to me and offers to take it off my hands for me. He has a truck. I give it to him, I thank him, and go on my way. Little did I know that the only thing of value in the entire car is the catalytic converter... Which is in the muffler. He wasn't helping me. He was exploiting the fact that I didn't know what I had and taking it for himself. That's what this is like. That's what it looks like. That's what it seems like. I'm not just 'Being a contrarian to be a contrarian'. This is pretty blatant and public exploitation that YOU are signing off on."

Muffler backfire

When a girl is giving you a blowjob, and while choking on your dick, she accidentally farts.

So my girl was choking on my cock, and had a little muffler backfire.

I think my girl had to shit, because while she was gagging on my cock, she kept hitting with a muffler backfire.
