The Sardaukar were created by Frank Herbert in his 1965 novel Dune as the Padishah Emperor's elite military force, feared across the Imperium. Their chant became widely recognised after Denis Villeneuve's 2021 film Dune, in the Salusa Secundus sequence where rows of soldiers chant during a ritual before deployment. Clips of that moment spread online as a shorthand for overwhelming power and dread. Creators still use it because the sound needs no context, the deep unified chanting alone signals discipline, danger and an enemy that will not be easily stopped.
