The sound comes from the theme song to the 1984 film Ghostbusters, written and performed by Ray Parker Jr. The song became a major hit alongside the comedy about a team catching ghosts in New York, and its call and response chorus stayed in popular culture for decades. Short clips of the bustin hook later circulated on soundboards and in meme edits, where the contrast between a cheerful pop vocal and anything spooky made it easy to reuse for reactions, Halloween posts and parody videos.
