The sound draws on The Exorcist, the 1973 horror film known for its possessed demonic voice, and reframes that voice as a scary phone call that gets cut off. That hang-up twist is described in Portuguese on soundboards in Portugal, where it circulates as a classic bizarre and dramatic joke audio. Online it spread through meme pages and short clips rather than a single official release. It stays popular because the reference is instantly recognisable, the call format fits pranks perfectly, and the short length makes it easy to reuse.
