Turkey slap is a sexual behaviour in which a male slaps another person's face with his penis (the "turkey"). 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. The turkey slap draws its name from the resemblance of the male's scrotum to the wattle under a turkey's neck.
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.[1][2]
