In Chapter 4 of NARUTO, Kakashi uses a technique called “1000 years of death” on NARUTO. In fact, this is a type of prank played by Japanese children, especially boys. If you are a Japanese male, you are likely to have experienced it or done it regardless of age or gender.
1000 years of death is “Kancho!” in Japanese
Kancho” is a prank commonly played by children in Japan. The word “kancho” comes from the Japanese word “kan” which means enema, and “cho” which means to poke. In the prank, the child makes a gun shape with their hands by crossing their index and middle fingers, and then quickly pokes another person’s anus with their two fingers while yelling “kancho!” as a surprise attack. The prank is typically done to friends or classmates as a way to shock or embarrass them. However, it is generally considered inappropriate and can be seen as a form of harassment, so it is not encouraged.
The plunk widely used in Japanese comic
This “Plunk” is a widely used in Japanese manga, often used as a humorous gag.
For example, Takabane uses it in Chapter 169 of Jujutsu Kaisen,
Chapter 169 of Jujutsu Kaisen
and it also appears in Slam Dunk.
The reason for this is because of its comical appearance and the psychological shame felt by the person on the receiving end of the strike. However, above all, the physical damage is thought to be the most significant factor. I too have experienced this during my childhood, and it was so intense that I was unable to move for at least 30 seconds.
