Nah I'd Win is a exploitable meme based on a panel from the 221 chapter of the manga Jujutsu Kaisen. In it Gojo Satoru makes a call back to the third chapter of the series in which right before fighting the main antagonist, he claims that he is going to easily win against them despite the fact that many perceive him as the stronger of the two. Spoiler Alert: This proved to be false, with Gojo getting bisected by the main antagonist Ryomen Sukuna and dying.

The meme spread around late 2023 with numerous redraws with other characters from the series, most notably the villain Jogo who got his but kicked by both Gojo and Sukuna.
