The clip comes from Shrek, the animated film whose dialogue has been remixed into reaction sounds for years across edits and soundboards. In Portuguese, the phrase became a compact way to answer claims that sound unrealistic, which helped it spread beyond the original scene into everyday meme use. Rather than explaining doubt or arguing back, users simply drop the line and let its sarcastic meaning do the job. It remains popular because the joke is universal, working for sports predictions, excuses, boasts and everyday promises that nobody expects to be kept.
