Soggy biscuit
Soggy biscuit (also known as ookie cookie, limp biscuit, wet biscuit, or cum on a cookie) is a male masturbation game reportedly played in schools, primarily British, where the participants stand around a biscuit masturbating until ejaculating onto it; the last person to do so must eat the biscuit. The game is also known in Australia as soggy Sao after the SAO brand of biscuits popular there.
Although "soggy biscuit" is not necessarily associated with homosexuality, since the game does not require mutual masturbation or other contact, the idea and practice of the game is in keeping with the spirit of adolescent sexual exploration associated by many in the UK with public schools (UK) or private schools (Australia).
Although the terminology may differ slightly, the notability of the game is such that variations on the theme are referred to in popular culture, examples including Stephen Fry's The Liar, the German film Crazy, the episode of Blackadder II, "Chains" and the episode of Drawn Together, "Freaks and Greeks".
