The title points to The Dark Knight, the Batman film whose dark, bass-heavy trailer sound became a shorthand for tension in online edits. Short rumbles in this style spread through fan videos, memes and soundboards, where creators reuse them to give amateur clips a blockbuster feel without needing a full score. Because the effect is instantly recognizable as serious and ominous, it remains a reliable choice for dramatic reveals, even years after the film's original trailer cycle.
