Kanchō (カンチョー) is a prank performed by clasping the hands together in the shape of an imaginary gun and attempting to poke an unsuspecting victim's anus, often while exclaiming "Kan-CHO!". It is a common prank among children in East Asia such as Japan, Korea, and China. In Korea it is called ddongchim (Korean: 똥침) In China, it is popularly called Qiānnián shā. The word is a slang adoption of the Japanese word for enema (浣腸, kanchō). In accordance with widespread practice, the word is generally written in katakana when used in its slang sense, and in kanji when used for enemas in the medical sense.
Because the act involves forced physical contact and can cause physical pain, it could be considered a form of physical assault or sexual assault, meaning the "prankster" could be charged with a crime.
