At the climax of sexual intercourse, the man ejaculates his man créme across the upper lip and adding an aristic swirl to each end. This gives the illusion that the women has a french mustache.
Dude my girl thought it was funny to use teeth while doming me last night, but I set her straight. I slapped a french mustache on that bitch

When you use any spreadable medium applied to each side of your penis so that when you wang slap the recipient(they must be unaware or unsuspecting), it draws a mustache across their upper lip. Precision and timing is a must.
