Exterminate is the signature battle cry of the Daleks, the armoured alien villains from the British science fiction series Doctor Who, first introduced in 1963. The word became closely linked to the Daleks through decades of television appearances, audio dramas and revivals, and it is now one of the show's most quoted lines. Online, the short shout spread through fan edits, reaction videos and soundboards, where its robotic delivery makes it an easy shorthand for playful destruction, rejection or over-the-top villainy.
