A thin stream of semen shot across a woman's upper lip, resembling the pencil-thin mustache worn by superintendent/handyman Schneider on the TV show "One Day At A Time".
"My girlfriend was going down on me and turned her head at the last minute, and I gave her a Schneider Mustache."

A girl on the outside who seems to be wholesome, but upon closer inspection she turns out to actually be very promiscuous. She is disguising her true sluttiness, much like someone might use a musatche to disguise their identity.
I started dating this girl, and was about to introduce her to my mother, but when I brought her back to my apartment, she let me, and my roommates run a train on her. Turns out, she was a mustache slut.
