What is "turkey slap"

n. (context idiomatic English) The act of hitting someone in the face with one's penis.

Turkey slap is a sexual behaviour in which a male slaps a partner's face repeatedly with his penis. While the act of hitting another's face with the penis can be a sexual act, the term "turkey slap" refers to the act when performed in a non-sexual way either playfully or to shame, degrade or harass the victim. More recently this has been popularized in the Netherlands in the form of Swaffelen.

The term gained notoriety in Australia during 2006, after two male contestants in the Big Brother reality TV series performed the act on a female housemate. In the ensuing controversy, the male housemates were expelled from the house and contest for violating the show's terms of agreement.
