Often referred to as a sexual maneuver in which the male has oral intercourse while driving with a woman while she is on her period. She then bleeds on his face, and then the female gives the male a handjob/blowjob until semenal excess is spewed on the males own face. Then he holds his head out the window while driving until it dries.
This was part of an actual McDonald's commercial in Australia, no joke.
Rumored to be a close relative of Pennywise the Clown.
