The Mythical Griffon refers to the sexual act where a male pulls out of the female right before ejaculation (typically in
the missionary, cowgirl, and other related positions where the participants are facing each other) and cums into one's hand and simply, openhandedly, slaps the female across the face, or bitch slaps her, unexpectedly thus splattering the semen all over the female's face hopefully to get it in the eyes, mouth, ears, nose and hair.
Can also be
accomplished using the "Cymbal" effect: a two handed Mythical Griffon via Doggie Style by clapping one's hands
on the face of the female unexpectedly after having came in both hands and rubbed together as if playing the Cymbals. Sometimes referred to as the Cymballic Mythical Griffon.
