I was about to get some of that fine ass pussy over there until Paul came up and started talking about Star Wars again, he's such a muffler.

Something that shouldn't be loud.
Ricer: Oh yeah I just got a loud muffler for my car so people will think my car is cool because it has a loud exhaust but I'm too poor to afford a real powerful car!

Me: ......You're an idiot.

When in a public bathroom one takes a wad of toilet paper (shit tickets); and holds it over ones asshole to hide the explosive fart and or shit that is about to rumble the bowl.This act can save one much embarrasment especially on a first date or while visiting the in laws at their tiny camper.

Be cautious a muffler may be a bit messier than the standard crap, but may be used in emergencies with guaranteed results.
ex 1.)*noun - Once in the bathroom,I decided to use a muffler after holding in that fart the whole way to his apartment.
ex 2.)* verb - Joe put a muffler on his tailpipe so his mother in law would not be offended by his morning dump.

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!
