This sound comes from League of Legends, where the announcer plays a shutdown call when a champion on a kill streak is finally eliminated. Because the term is so recognizable to MOBA players, the clip spread into gaming edits, streams, and short-form memes as a quick way to signal that someone got punished after dominating. It still works well outside League because viewers immediately understand the idea of momentum being broken, similar to how the roblox oof became a universal fail cue.
