The 'Hentai Tags' meme format involves overlaying specific genre tags—commonly found on adult image boards and search filters—onto fictional characters or real-life photos. This trend gained traction on platforms like Twitter and Reddit as a way to ironically categorize characters based on their personality or to mock specific internet tropes. By applying these specific labels, creators add a layer of dark humor or meta-commentary to the image, often highlighting absurd character traits or creating humorous 'expectations vs reality' scenarios. It has become a staple in the anime community for its versatility and recognizable visual style that mimics the UI of popular adult media databases.
