The World Cutting Slash comes from Jujutsu Kaisen, where it is Ryomen Sukuna's ultimate extension of Dismantle, a slash that cuts through space itself rather than just its target. It became infamous during his battle against Satoru Gojo in the Shinjuku Showdown arc, where its unstoppable nature changed the course of the fight. Clips and fan edits of the moment spread widely across TikTok and YouTube, and the sound is now shorthand online for an attack that nothing can block.
