The sound comes from Tokyo Ghoul, the dark fantasy anime and manga series centred on Ken Kaneki, a young man transformed into a half-ghoul. Fans clipped his desperate anime scream from the series and shared it across anime edits, reaction videos and soundboards, where its raw Japanese delivery made it stand out from English dub clips. Because it is only about two seconds long, it is easy to drop into short-form videos, and it remains popular as a shorthand for snapping, frustration and overwhelmed anger in anime meme culture.
