Doppelganger Week is a social media phenomenon that originally gained massive traction on platforms like Facebook, where users change their profile pictures to a celebrity they purportedly resemble. While the trend began as a sincere way to celebrate likenesses, it quickly evolved into a meme format where people ironically compare themselves to completely unrelated or humorous characters for comedic effect. This meme captures the vanity, humor, and sometimes delusional nature of finding one's 'twin.' It is widely used to highlight uncanny resemblances or to mock the stretch people make when claiming they look like a Hollywood A-lister during the annual social media event.
