look up any word, like boo:
When one, after anally penetrating one's partner, wipes one's fecal encrusted member across the partner's upper lip. Also called a "Dirty Sanchez". Can also be called a "Trojan Mustache", if partner is unsuspecting.
Rob: I was having sex with your mother last night and she surprised me with a Greek Mustache.
Bob: How dare you! In that context it's called a Trojan Mustache!
Rob: Sorry. Either way, your mom's got a dick. Not cool.
Bob: How dare you! ......!
