A sexual act comprising of a woman (without a penis or any protruding penis-like object in the genital region) thrusting her hips vigorously upon a male's tailbone so as to achieve orgasm through
clitoral stimulation. Tailboning is a common pastime amongst nymphomaniacs and sexual deviants alike. Often a quick,
random action, tailboners get some of the best orgasms known to man and to the Pagan gods.
