muffler vibrator

When you fart while some is eating your ass, you make their lips vibrate on your butthole.

Katie was talking too much so I gave her a muffler vibrator.

Muffler

A classification of modern homosexual. A buff gym rat at a pool party, who wears shirts sizes to small - when if ever he bothers to wear a shirt. Often sporting large poorly done tribal tattoos decided upon when sped up or on poppers. Also as a species they can be quite loud. Also there is a high transormation rate into your standard bear with age.

That pack of mufflers totally just cruised you.

Do you smell that? Is it suntan lotion and sperm? Must be a pack of mufflers!

Mufflers

The people who try to talk to you while you have headphones in

Mufflers: *blah blah blah*
You: What did you say
Mufflers: I said could you help me clean

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"
