The scream comes from Star Wars: Episode III – Revenge of the Sith from 2005, when Darth Vader learns that Padmé has died and cries out in anguish beside the Emperor. The line quickly escaped the film online, becoming a shorthand reaction alongside the regular Darth Vader NOOOOOOOOO version with music. Editors kept sharing a clean cut without the score so the voice could sit over any footage, and that flexibility helped it survive as a meme sound for dramatic losses, parodies, and reaction videos.
