Rasengan is a signature technique from Naruto, the manga and anime created by Masashi Kishimoto. The move became one of the series' most recognisable attack calls, so short clips of it spread widely in anime edits, gaming montages and meme videos. Online, people use the sound to signal a concentrated burst of power or a decisive finishing move. It remains popular because even a very short snippet instantly communicates Naruto, action and impact to viewers who know the series.
