What is Brown Mustache?
1.
After having a shit, use your fingers to wipe. Then use your fingers on someone's face to create a Mustache of shit. Obviously this is best done when the person is asleep. When the person wakes up they will initially have no idea where that nice smell is coming from.
"Let's give Paul a brown mustache while he's asleep"
