Chidori comes from Naruto, the manga and anime series created by Masashi Kishimoto. In the story it is a high concentration lightning technique created by Kakashi Hatake and later taught to Sasuke Uchiha, who uses it as a signature attack. Its name means thousand birds, a reference to the chirping crackle the electricity makes in Japanese. Clips of the charge sound spread through anime edits, AMVs and gaming videos, and it remains popular because fans instantly link the noise to Sasuke, Kakashi and fast, decisive strikes.
