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 Asian countries such as Japan. In Korea, it is called ddongchim (Korean: 똥침). In China, it is popularly called qiānnián shā (千年殺), which was derived from the jutsu technique in the manga and anime series Naruto, in which it is known as 千年殺し (sennen goroshi, meaning "one thousand years of death"). The word "kanchō" 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.
In English-speaking countries, the prank is known as goosing or “yemming”.
