muffle fart

When someone holds toilet tissue against their ass in the restroom to stop excessive noise.

It was the first time I was at her house so I used the bathroom and decided to muffle fart, because I really liked her.

Coffee Can Muffler

An over sized muffler on a car, typically driven by wanna-be street racers that only care about how their car looks.

I hate those posers that just throw a coffee can muffler on their car.

fatal sky muffler

This is a dangerous maneuver that should only be tried with adult supervision. A guy jumps out of a plane with a parachute on, holding on to a girl that does not have a parachute but is “trusting the guy” to hold on. He is thrusting her from behind in a violent doggie style motion, blowing his load on the girl’s bare back. As the last few drops dribble out, he pulls his parachute letting the girl go watching her fall to a brutal death. Yet extremely difficult to pull maneuver off, a few successful attempts have been recorded recently. -Andy K.

Lenny tricked Jen into pulling off a fatal sky muffler. She thought he was going to hold on to her.

Mufflerectomy

The act of totally removing the muffler and resonator from a vehicle and replacing with straight pipes, thus reducing the restrictions on exhaust flow, and giving the car a deeper, nicer exhaust sound. Usually done when new performance mufflers either do not exist or are too expensive.

Dietrich: Dude, there aren't any sport exhaust systems for my Jetta TDi.

Stefan: Don't worry about that crap, just give it a mufflerectomy.
