It is when a male human jerks his penis off and ejaculates onto a female human's upper lip then he proceeds to piss on her upper lip thus turning the jizz/semen to a yellowish goo the result is the formation of a golden yellow mustache on her upper lip.
I gave her a golden mustache at the party because I was ragin horny and wanted to get it on then we did it in her parents bedroom and I pulled out my rager and gave her a Golden Mustache.
