The 'Et Tu, Brute?' meme draws its name and imagery from the famous line in William Shakespeare's play Julius Caesar, depicting the tragic moment the Roman dictator realizes his close friend Brutus is among his assassins. In internet culture, the template typically uses classical paintings of the assassination to symbolize a sudden or unexpected betrayal. Whether it’s a friend stealing a fry after saying they weren’t hungry or a laptop forced update during a presentation, this meme perfectly captures the dramatic sting of being 'stabbed in the back.' It remains a staple for expressing relatable disappointment and humorous treachery across platforms like Reddit and Twitter.
