A dirt mustache is when you eat a girl's dirty asshole and get residual feces all over your upper lip.
My girlfriend asked me to eat her ass last night and it was dark and when i turned the lights on i had a dirt mustache.

Get the Dirt mustachemug. Basically when someone wipes a finger all the way down thier ass crack and then wipes it under someones nose.
This is something you may want to do to someone who is passed out drunk. When they breathe in, they smell your ass.
