The line comes from The World Ends With You, the action role playing game developed by Square Enix and Jupiter and first released for Nintendo DS in 2007 in Japan and 2008 internationally. Set in a stylised Shibuya, the game became known for its distinctive art, music and expressive voiced reactions during its story battles. Short exclamations like this were later clipped by fans for reaction edits and soundboards, and interest renewed with the Final Remix release on Switch in 2018 and the sequel NEO The World Ends With You in 2021.
