When after engaging a girl in anal sex, she proceeds to spray diarrhea all over you. It is actually a mix of semen and feces which has an odor similar to very old muffler grease.
I was butt-fucking Pamela after she ate 3 steak soft tacos. Right when I thought things were cool, she blew her dirty muffler all over my cheast. I'll never eat mexican food before sex again.

Lana has a blue waffle, a purple sock, the clap, the drip, and crabs at the same time. So Lana has a Rainbow Muffler.

The act of a girl lying on her back and mashing her boobs together while her significant other sits on them and farts.
Once she got her breast augmentation, it really created a higher pitched sound when I gave her a boob muffler.

Someone who goes to either car or motorcycle meets and waits for a ride. Usually females are known to hang out. Resembles a groupie just hangs out for the atmosphere and ride.

When you cup a wad of TP in your hand and cup your butthole while you're sitting on the toilet to muffle your fart sounds. Works like a charm!
