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.

Randy was prone to excessive muffler marks so he switched from tighty whities to dark boxers.

guff muffler

A device worn beneath outer garmets to arrest the foul stench coming from ones butt when farting and to reduce the sound from reverberating round

Farts smell and sound much worse when in the shower than sat in the car with a guff muffler (clothes) on
