The Kamehameha comes from Dragon Ball, the long-running manga and anime series created by Akira Toriyama, where it is the signature energy attack of Goku and the Turtle School. The technique is charged in the hands and fired as a beam, and it became one of the most recognisable moves in anime as the series spread worldwide through television, video games and merchandise. Online, fans clipped the shout and blast for edits, reaction videos and memes, keeping it familiar even to viewers who have never watched a full episode.
