This article is about the sex act. For information about the magician, please see Houdini. Please see discussion page for more info.

The Houdini is a slang term for an obscure and degrading sexual activity performed during doggy style sex. It is classed as an urban legend because the term is propagated because of its shock value rather than as a description of an actual act that has been performed.

Supposedly, it is performed by the male, by spitting on the female's back head or neck immediately prior to orgasm. This is supposed to make the female believe the male has ejaculated, causing her to turn around and be surprised and degraded by the orgasm released by the male on her body seconds after.

This activity is also known as the "Pump Fake", or the "Spitting Dragon" (not to be confused, however, with the Angry Dragon or Alaskan Fire Dragon ).
