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.
Music to tailbone to: Fela Kuti, Death Grips, Charles Mingus
