dirty muffler

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.

Dirty Muffler

The act of farting while you have chicken grease (mixture of butthole sweat and leftover poop) between your thighs.
