The line comes from Shrek, the animated film about an ogre whose unlikely friendship with Donkey, called Burro in the Spanish dub, drives much of its comedy. In Spanish-speaking meme culture, the short exchange became a shorthand reaction for feeling slighted, because the wording is direct and easy to reuse outside the film. Shared through soundboards, reaction videos and short-form edits, it survives as a quick way to signal mock offence without needing any plot context, especially when the joke depends on an exaggerated response to a minor comment.
