(O)Possum Muffler

When a vehicle lacks a muffler, or is otherwise intrinsically obnoxious or obnoxious by virtue of its owner, and vigilantes or society at large decide to tie the carcass of a dead opossum to the vehicle to display distaste for the vehicle or its driver.

"F--- that guy, if he declines his engine in front of the house again, he's getting an (o)possum muffler."

"We gave the Purple Avenger a 'Possum Muffler."

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.

Hot Muffler

When you take a shit that's either huge, or after eating spicy foods, causing your anus to bleed.

That spicy burrito gave me such a hot muffler.
