Ratboy Genius refers to a series of surreal 3D animations created by artist Ryan Dorin, featuring a recurring cast of characters like Ratboy, Little King John, and the Happyman. The series gained massive internet fame primarily through the 'Potato Knishes' music video, which became a viral sensation due to its uncanny valley visuals, repetitive singing, and bizarre lyrics. Users typically use the Ratboy Genius template to evoke a sense of 'weird core' or surreal humor, often pairing the unsettling animations with nonsensical text or absurdist observations. It remains a staple of early 2010s experimental internet culture, representing a unique intersection of low-poly 3D art and avant-garde storytelling.
