This legendary sound effect originated in WWE as the opening note of The Undertaker's entrance theme, debuting in 1990. The ominous toll was designed to strike fear into opponents before the wrestler even stepped into the ring. Over the decades, the chilling gong transcended wrestling to become a viral internet meme. Today, creators use it to signal an unstoppable threat or dramatic finality. While some videos use a lighter Taco Bell Bong for comedic surprises, this heavy gong is reserved for suspenseful moments, similar to the classic dun dun dunnnnnnnn effect.
