Bass drops became a defining feature of dubstep and electronic dance music in the late 2000s, where producers built tension then released it with a heavy low end hit. The technique moved into movie trailers, sports highlights and online video editing, and short isolated versions spread on soundboards and in meme culture. Creators borrowed the drop as a ready made dramatic cue that needs no context, so it now appears far outside music, marking reveals, fails and exaggerated reactions in short form videos.
