Sekiro: Shadows Die Twice launched in 2019 from FromSoftware and built a reputation for punishing boss fights where every victory feels earned. Clips from the game spread quickly through gaming communities, streams and short meme edits, and exaggerated reaction sounds became a shared shorthand for that relief and hype. The woooo yell fits that culture perfectly, borrowing the energy of a hard fought win without needing any context from a cutscene. It remains popular because gamers instantly connect the sound with triumph after repeated failure.
