Spin the bottle is a party game in which several players sit/stand/kneel in a circle. A bottle is placed on the floor in the center of the circle. A player spins the bottle, and must kiss the person to whom the bottle points when it stops spinning. It is popular among teenagers. There are a very large number of variants. One variant is that instead, two players must hug within 5 seconds, otherwise, they have to kiss in 10 seconds and if the 10 seconds are up and they haven't kissed, they have to French kiss. Variations allow for other tasks to be accomplished. It can also be used to decide the player for another game such as Truth or Dare? Certain variations also include penalties.
Even though it might be played occasionally by young teenagers, its fortune has declined starting from the 1990s. Spin the bottle was very popular among teenagers over the second half of the 20th century because it fostered "sexual" interactions between boys and girls. It has even been defined as the party game of choice for glandularly excited high schoolers.Spin the bottles has been nowadays mostly superseded by drinking games.
The exact origin of this game is currently unknown even though it seems reasonable that the game was invented in the USA not earlier than the first half of the 20th century. The earliest known written record of this game dates back to 1925. Written records of a similar game, called Bottle of Fortune, are available dating back to 1922. From the above sources it follows that the game was already well known and popular among children during the 1920s.
