A commonly forgotten elicit teenage sex game. The homoerotic equivalent of Duck Duck Goose; it involves one erect cock and several other steamed cucumbers. The player (gender is personal preference) must be blindfolded and tries to call out the cock among the cucumbers. Note: Alcohol consumption can either make this game good fun or a complete disaster.

Child (with a look of shame and anxiousness): No... we played Cucumber Cucumber Cock...
