When one takes a shit and doesn't clean themselves, it dries, and another then has anal sex with the dry, dirty, poop butt.
"After drinking and chinese food last night, we got back to my place and (i didn't have and toilet paper) we started getting freaky, needless to say i got the crusty muffler."

Along the lines of Blinker Fluid, it is used to confuse people who know very little about cars. This belt does not exist, as it would be unnecessary to the exhaust system.

Dave, "Did you remember to tighten the muffler belt within the last 3000 miles?"

Have your chick lay on her back, straddle her face spread out your ballsac while covering her mouth and nose. When she tries to breath, the air escaping her mouth shall make a muffled sound as it escapes the seal of your nutsac. This move was born on 11/15/2012 by JCassady in Baghdad, Florida. Named with the help of B. Cobb, and M Spratt on 11/16/2012. Also perfected by Z. McAuthur on 11/16/2012 thanks for the help team...

a device or appliance yet to be invented to 'muffle' the sound of your shit hitting the water and/or associated/simultaneous farting.
"i could have used a shit-muffler this morning, that curry and 10 beers to wash it down i had last night really made things awkward at the handbasins as the airport toilets were bustling"
