The Miguel's Guitar meme originates from the 2017 Disney Pixar film 'Coco,' specifically the scene where the protagonist, Miguel Rivera, finally gets his hands on the legendary white guitar of Ernesto de la Cruz. This visual captures the pure joy and determination of a character pursuing a forbidden passion against all odds. On the internet, the template is widely used to represent the moment someone discovers a new interest, hobby, or career path that they immediately decide to make their entire personality. It resonates with audiences because it balances the heartwarming theme of the movie with the relatable human tendency to go 'all in' on a newfound obsession.
