Boston Muffler

When you're penetrating someone anally and they fart, creating a muffler sound.

Brian "Did you go give it the chick you met at the bar last night"

Tony "Yeah, I gave it to her from behind. She even gave me a Boston Muffler. The vibration was amazing"

muffler masters

The gayest group of men you’ve ever met. Until the clothes come off. Then suddenly everyone goes back to being hetero. Very strange

You ever been to muffler masters? So weird

Mullet Muffler

When you are eating out a dump truck of an ass from behind and she lets out a gasser that blows your party in the back like a midwestern tornado.

Zach was nose deep in a heifer of a woman when she let one loose that blew his hair mud flap back like a wind sock. He knew he had received a Mullet Muffler.

Mufflering

The act of taking a pull from a vaporizer tank without use of a protective drip tip and/or top cap.

Basically putting the lips on hot metal tube and inhaling vapor.

Dude...I'm so high, I almost started mufflering my vape RDA without the top cap. My lips would have been burnt and blistered like a herpes outbreak.
