The phrase comes from Jujutsu Kaisen, where Gojo Satoru answers a question about facing Sukuna with total confidence. A popular fan translation shortened his reply to Nah, I'd win, and that wording spread far beyond the manga in 2023. Screenshots of Gojo were edited onto games, anime fights and everyday challenges, with the line becoming shorthand for delusional confidence. Short voice versions followed the image macro online, letting editors drop Gojo's bravado into any matchup in a single instant beat.
