The bell comes from WWE and the entrance of The Undertaker, the wrestler whose dark, deadman character made a slow funeral toll one of the most recognisable sounds in wrestling. As his entrances were replayed on television and shared online, the toll became shorthand for doom, death and dramatic arrival beyond wrestling itself. Meme creators on YouTube and TikTok began using it like a dun dun sting to mark reveals, failures and ominous entrances. It remains popular because the sound needs no explanation: one toll instantly tells viewers that something serious, spooky or hilariously doomed is about to happen.
