The line comes from Star Wars, where different characters say a version of 'I have a bad feeling about this' in almost every film in the saga, usually just before danger or a risky escape. It became a running joke for fans because it appears so often, and it later spread far beyond the films as a meme, reaction sound and short clip shared on social media. Creators still use it today because the phrase is instantly understood even by people who have not seen every film, making it a quick way to warn that trouble is coming.
