This sound refers to Satoru Gojo's amplified Hollow Purple technique from Jujutsu Kaisen, commonly searched as 200% Hollow Purple by manga readers and anime fans. The phrase became especially popular in online edits, versus debates and short-form videos that highlight extreme power moments. Creators use it as shorthand for an attack that completely overwhelms the scene, much like Za Warudo in anime edits. Its lasting appeal comes from how quickly it communicates hype, scale and confidence to viewers who know the series.
