One Thousand Years of Death

Thousand Years of Death This is a very simple jutsu with a very over-dramatized name. All the user does is forcefully plunge their index and middle fingers into their opponent's anus, usually causing severe constipation among other things. Its rank varies from user to user based on just what they do with it. For example, Kakashi used it to launch Naruto a ridiculous distance (perhaps propelling him with chakra). Naruto later figured out the true purpose of the jutsu: it is used in conjunction with a pointed object (usually a kunai) to attack the blind spot of an opponent. When combined with explosive tags, it can even kill an opponent. The technique is similar to a childish prank known as a kancho.
 * Type: E-rank, Offensive, Short range (0-5m)
 * Users: Hatake Kakashi, Uzumaki Naruto

The official name for this technique is "Sennen Goroshi". However, the name is sometimes thought erroneously to be "Sennen Gurushi" (千年苦し), meaning something along the lines of "Thousand Years of Pain". It could be construed that the original fansubbers, when translating the fourth episode, in which the jutsu debuted, heard the name as "Sennen Gurushi".
