The crash cymbal is a standard part of a drum kit, played by striking a large suspended cymbal with a stick to produce a loud, explosive accent. Drummers in rock, jazz, orchestral and pop music have long used it to mark the start of a chorus, the end of a song, or a dramatic moment. Online, that familiar live-music punctuation was borrowed by video editors and meme creators as a ready-made sound effect, where its instant recognisability makes even a small moment feel big, final and intentionally over the top.
