The Undertaker gong is best known from WWE, where it became a signature part of The Undertaker's entrance presentation and overall persona. Over time, that single ominous strike spread beyond wrestling clips into meme culture, especially on short reaction videos and dramatic edit formats. People recognize it instantly because the sound communicates dread and spectacle with almost no setup. Its staying power comes from how quickly it can turn an ordinary moment into something that feels huge, serious or darkly funny.
