(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."

Bloody Muffler

Forcefully ducking down a puckered butthole resulting in a bloody mess

We found a trail of blood leading to AJs bedroom and he was curled up in a ball sucking his thumb. Looks like Mike really gave him a bloody muffler this afternoon
