This sound is best known as an online reaction clip rather than a clearly documented quote tied to one famous source. It spread through short meme edits and reposts where creators use “death threats” as an ironic shorthand for extreme backlash over something trivial. The format fits platforms built around fast punchlines, especially short-form video and meme compilations. It is still used because the phrase is instantly understood, the escalation is obvious, and it works well with abrupt cuts, caption jokes, and awkward silence.
