Catholic Church code phrase used by Priests whilst in the confessional instructing the unwary confessee to "Kiss the Jesus." This is always accompanied by the sound of a zipper coming down in a rapid manner and a loud, "BOING-ing" sound as the erect penis of the Priest, at the sight of a ten year old boy, pops out of his Cassock.
Gerald, Ten Year Old Boy: "Forgive me Father for I have sinned. It has been one week since my last confession."
Catholic Priest: "Say five Our Fathers and One Hail Mary and KISS THE JESUS."
