The Surprised Frodo meme stems from Peter Jackson's 'The Lord of the Rings: The Fellowship of the Ring', capturing the wide-eyed, stunned expression of Frodo Baggins, played by Elijah Wood. It typically features Frodo with an expression of pure disbelief or sudden realization. The image went viral across platforms like Tumblr and Reddit, used by fans and non-fans alike to react to shocking news or unexpected plot twists in real life. It has since become one of the most enduring reaction images from the LOTR franchise, symbolizing the universal feeling of total shock.
