Contra Code 

(Sex act) While performing oral sex on a woman, the tongue manipulates the clitoris like a joystick moving up, up, down, down, left, right, left, right- the same directional commands used in the infamous "99 lives" cheat in the old 80's Nintendo game Contra. Since the same cheat works in the classic Castlevania, this could also be referred to as The Castlevania Code, or even "Contralingus".

"I had my face in her crotch for a good ten minutes, but once I entered the Contra Code she squirted so hard I saw it arc right over my shoulder"
