The title references The Human Centipede, the 2009 Dutch horror film that became notorious online for its disturbing premise and the shocked reactions it provoked. Clips and sounds built around watching it spread as a shorthand for extreme disgust, well beyond horror fans. This short reaction fits that tradition, sitting alongside other revolted staples like eww brother eww in meme edits. It remains useful because the response is universal, so creators can drop it over anything gross or cursed without needing to explain the film itself.
