The line comes from Ray Parker Jr.'s theme song for the 1984 film Ghostbusters, a funk-pop hit built around the team's ghost-catching catchphrase. The full song became closely tied to the franchise, returning with sequels, reboots, and Halloween playlists, while the short lyric took on a second life online. Creators lift the two-second hook for memes and short-form edits because it is instantly recognisable, upbeat, and easy to drop over a win, a reveal, or a confident moment without needing any context from the film.
