A person who tries to eat your face off while making-out.

A "dirty sanchez" is when you see someone who looks like they are dressed up as a mexican for halloween, but then you get closer. Then you smell something and realize it might be poo poo, or gushie. It's so gross you feel like throwing up. Some people call it dirty sanchez, some people call it stinky stevie, but it's a poop mustache...a painted poop mustache. GROSS!
I almost threw up when I realized Lomita had a poop mustache, known as a dirty sanchez, that I could actually smell when talking to her.
