v. the sexual act of a woman jerking off a man into her hand. When the man ejaculates and he is recovering from his orgasm the woman takes his cum and swipes it above his lip, making a moustache, while simultaneously calling out "semen sanchez."
Kim gave Dorian a semen sanchez last week and he got pissed.
