Butt Muffler

A very audible blast of air from the anal orifice during anal sex.

Dude, Sally kind of freaked me out with that unexpected butt muffler last night.

muffler lip

Someone who smokes very heavilly - usually has very bad breath.

Their diet of coffee and cigarettes gave them a nasty case of muffler lip.

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

1. A mechanism put on cars to lower the intensity of the sound otherwise produced.
2. One who engages in licking a woman's vagina.
3. Quite possibly THE most fun word to say in the entire english language.

1. I took off the muffler on my car and now it doesn't sound like some pussy owns it anymore!
2. (some things are better left unsaid).
3. Say it like you mean it. Muff. lir. Muffler. MUFFLER!!!!!!!!!!!!!

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)
