The 'Nah, I'mma Do My Own Thing' meme originates from the 2023 animated film Spider-Man: Across the Spider-Verse. The line is delivered by Miles Morales during a climactic moment when he rejects the rigid destiny (the 'canon event') imposed on him by Miguel O'Hara and the Spider-Society. It represents a powerful act of defiance against fate and authority. In internet culture, the meme took off immediately after the film's release, used to illustrate situations where someone chooses a non-conformist path or ignores expert advice to follow their own intuition. It has become the ultimate template for celebrating individuality and subverting expectations.
