The bell comes from the entrance of The Undertaker, the long-running WWE character portrayed by Mark Calaway, who debuted as the Deadman in 1990 and became famous for dark, funeral-themed entrances. The tolling gong became his signature cue, signalling that he was about to appear in a darkened arena. As wrestling clips spread online, editors lifted the bell for memes, reaction videos, and dramatic entrances far beyond wrestling, because it instantly frames any arrival as ominous and final.
