The Princess Bride meme template primarily features the character Inigo Montoya, played by Mandy Patinkin, from the beloved 1987 adventure-comedy film. The most famous iteration stems from the scene where Inigo responds to the character Vizzini’s constant exclamation of 'Inconceivable!' by stating, 'You keep using that word. I do not think it means what you think it means.' This specific frame and dialogue became an internet sensation in the late 2000s, used as a clever reaction to people who misuse vocabulary, technical terms, or political jargon. It has since evolved to cover various scenarios where someone is confidently incorrect, making it one of the most enduring and versatile movie-based reaction memes in digital history.
