The Exorcist is a 1973 American horror film about a young girl possessed by a demon, and its music and sound design have become shorthand for demonic horror ever since. Clips linked to the film circulate widely on social media and in short-form video, where creators reuse them to turn an ordinary moment into something sinister in seconds. Because audiences already associate the sound with possession and exorcism, it needs no explanation, which is why it remains a popular choice for Halloween edits, horror reactions and spooky memes.
