A sexual act that occurs when a man ejaculates into a dusty box fan and creates a chunky white substance that covers his partner
A mischievous smile crossed his face as he saw it there in the corner. The box fan in his room hadn't been cleaned for months. Longdusty tendrils hung from its blades like jungle vines. By the end of the night his date would be covered in Scranton tartar sauce.
1.I heard the Stacy was telling nasty rumors about me. I'm gonna have to steal that (censored)'s tartar sauce!
2.I'm in the mood to steal tartar sauce today. (less common use)
