Name: One Thousand Years of Death (千年殺し, Sennen Goroshi)
Type: E-rank, Offensive, Short range (0-5m)
Users: Kakashi Hatake, Naruto Uzumaki
Debut (Anime):Naruto Episode 4
Debut (Manga): Chapter 5
A very simple technique with an over-dramatic name, One Thousand Years of Death is little more than inserting one's index and middle fingers (similar to the Tiger hand seal) into the opponent's rectum, causing constipation and/or embarrassment. Characters that see the jutsu react oddly (Temari blushes and Gamakichi shows a look of disappointment), while those who have used or experienced the jutsu show great fear in it being used on them.
While seemingly useless, the technique can be useful if used correctly. During the first bell test, Kakashi was able to throw Naruto a great distance, probably propelling him with chakra. Naruto would later find out that the point behind the technique was to target the opponents blind spot, and when one substitutes their fingers for a kunai with an explosive tag, it can be a lethal technique. The aforementioned variant has only been used by Naruto.
