muffler marks

the residual shit stains in your underwear at the end of the day. Just like skid marks, but more apt to be from a possible shart.

When you have anal sex and the women farts during. When the guy pulls out a little poop comes with it and it's very stinky.

"Man Karissa did a number on me last night, she did that stinky muffler and I can still smell it."
