Boong-Ga Boong-Ga (Korean: 붕가 붕가, Japanese: 浣腸ゲーム kanchō geemu), also known as Spank 'em, is an arcade game developed by a South Korean company, Taff System. It is the first arcade game to simulate kancho, a children's prank popular in Japan where the victim is poked with two fingers in the anal region while distracted.
The game received infamy on the internet in 2001 for a badly-translated advertising flyer that promoted the game's peculiar spanking and kancho oriented gameplay. Boong-Ga Boong-Ga was reportedly designed for the Japanese market, and according to advertising material was well received at the 2000 Tokyo Game Show.
The object of Boong-Ga Boong-Ga is to score points by spanking or performing kancho on a model of a human posterior embedded in the game's cabinet. A plastic finger is attached to the machine for players to perform the latter.
The game features eight characters players can punish: "Ex-Girlfriend", "Ex-boyfriend", "gangster", "Mother In Law", "Gold-digger", "Prostitute", "child molester" and "Con-artist". During gameplay, the facial expression of the chosen character is displayed on a monitor.
The game also dispenses cards that rate players on their "sexual behavior", and for players who perform exceptionally well the machine will dispense a small plastic trophy in the shape of a pile of feces.
