The Gender Swapping meme trend surged in popularity with the rise of AI-powered photo editing apps like FaceApp, which allowed users to see highly realistic versions of themselves as the opposite sex. Social media users quickly turned these transformations into a meme format, often pairing original photos with their gender-swapped counterparts to express shock, attraction, or comedic irony. Beyond the filter craze, the concept is widely used in fandoms to imagine 'Rule 63' versions of fictional characters. Today, the meme serves as a versatile tool for commentary on identity, vanity, and the uncanny capabilities of modern image manipulation technology.
