When one proceeds to fellate a man w/ over grown pubes. Once she/he has taken the dick far enough into the back of her/his throat, her/his mouth will be right on the overgrown pubic hairs, resembling a mustache.
Dude - you know I don't give a shit about my ball-fro, so when I shoved my dick down Abby's throat, that bitch had a popsicle mustache!
