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
I was laying down and she was on top of me trying to fuck my ass with no dick. My tail bone wrecked that clit and she orgasmed for days. Tailboning gets me all the concubines.
