The 'Nah, I'd Win' meme originates from Chapter 221 of the Jujutsu Kaisen manga, featuring the character Satoru Gojo responding to a question about his potential defeat against the King of Curses, Sukuna. Despite the character's eventual fate in the story, the panel became a viral sensation in late 2023 across Twitter, Reddit, and TikTok. It is used both unironically to display supreme confidence and ironically to mock situations where someone's arrogance leads to immediate failure. The meme's popularity surged due to the community's creative 'brainrot' edits, where Gojo's face is replaced with other characters or objects while maintaining the signature smirk.
