The line comes from Shrek Forever After, released in 2010 as the fourth Shrek film. In the scene, a young fan nicknamed Butter Pants keeps asking a frustrated Shrek to perform his famous ogre roar, turning a simple request into a running gag. Clips and quotes of the exchange spread online as a meme, often paired with images of Shrek or used on their own as a demand for someone to perform. Its short, repeatable phrasing has kept it in soundboards and meme edits long after the film.
