The sexual act where one defecates on a partner's face, then proceeds to rub said faecal matter into the face with a back and forth motion of the buttocks. The buttock cleavage should form a groove into which the
nose slots, providing a guide for this motion.
This was allegedly the act to which
Meatloaf referred to in the iconic song lyric: "I would do
anything for love, but I won't do that".
Jim: "
Hey Randy, you know what Meatloaf wouldn't do for love?"
Randy: "Don't tell me, galleoning?"
