Scappoose Muffler

The Scappoose Muffler is local to residents of Oregon, whom upon leaving Portland for the coast, begin to get tired of their female companions chatter about 1/3 of the way to their destination while driving through Scappoose.
to quell the flow of words, the man whips out his cock and slams the head down on his johnson, thus muffling the flow of words and getting some piece and quiet.

Lucy wouldnt shut up this weekend on our way to the coast so I gave her a Scappoose Muffler and followed it up with an angry pirate.

Muffler bearings

A fictional term that bullies use when they ask questions or give maintance advice to ricers.

There is no such thing as muffler bearings however most guys who know nothing about cars can easily be convinced that it is part of their maintance.

Ricer: Is there anything I need to know before I install my new exhaust system?

Bully: Make sure to grease those muffler bearings before the install (bully laughs under his breath)

Dutch Muffler

Similar to the Dutch Rudder. When a partner assists you with placing your own fingers in your anus and continues thrusting your hand for stimulation.

She wouldn't have sex with me but i did get her to give me a dutch muffler.

My asshole is still sore from that dutch muffler my girl gave me last night.
