The phrase comes from Ray Parker Jr.'s 1984 Ghostbusters theme, where the chorus line about bustin' making him feel good became one of the film's most quoted musical hooks. Online editors later isolated and tripled the word, turning it into a compact soundboard loop for streams, edits and Halloween posts. Its appeal is the instant recognition: even without the full song, the repeated hook recalls proton packs, ghosts and the original comedy, making it a shorthand joke that still works in short meme videos today.
