The clip comes from the Spanish-language version of the 1990 television adaptation of Stephen King's It, known in Spanish as Eso. The phrase 'mátalos a todos' translates literally as 'kill them all', a blunt villainous command that fits the story's menacing tone. As a short soundboard clip, it has circulated among Spanish-speaking horror fans and meme editors who recognise the line instantly, even without the surrounding scene. Its brevity and direct wording have kept it useful for dark jokes, reaction edits and Halloween-themed videos long after the original broadcast.
