The scream comes from Star Wars: The Phantom Menace from 1999, where Obi-Wan Kenobi, played by Ewan McGregor, cries out as his mentor is struck down in the final duel. Fans lifted the moment from the film into Star Wars edits and reaction videos, where its over-the-top grief made it perfect for mock tragedy. It is often paired with Darth Vader's Nooo in Star Wars reaction compilations, and it remains popular because the sound alone tells the whole story of a plan collapsing at the worst possible moment.
