Exterminate is the signature battle cry of the Daleks, the robotic villains of the British science fiction series Doctor Who, who first appeared in the 1960s. Spoken in a harsh electronic voice, the word became shorthand for ruthless, unstoppable destruction and has been quoted, parodied and remixed for decades. This low-pitched version circulates online as a short soundboard clip, where creators use it as a quick villainous punchline. Its instant recognisability keeps it popular in memes, gaming videos and Doctor Who edits long after its television debut.
