Corecore, also known as 'Nichedore,' is a subgenre of internet art that emerged on TikTok around late 2022, characterized by its focus on hyperreality and existentialism. It typically involves a fast-paced, maximalist montage of media clips, news reports, and cinematic scenes that evoke a sense of overwhelming emotion or societal critique. As a meme format, it moves away from traditional irony and toward a more sincere, albeit bleak, reflection on late-stage capitalism and the digital experience. By using the Corecore style, creators turn everyday sensory overload into a form of visual poetry that resonates with the collective anxiety of the modern generation.
