Bad Romance was released by Lady Gaga in 2009 as the lead single from The Fame Monster, and its opening vocal quickly became one of the most recognisable intros in pop music. The short chant-like 'ooh' sets the song's dark, theatrical tone before the electronic beat begins, making it easy to lift out of context. Online, creators began using the two-second clip as a cue for dramatic entrances, reveals, and edits, especially in short-form video. Its brevity, instant recognition, and built-in tension keep it useful years later.
