Dota 2 is Valve's long-running team-based battle arena game, built around five-player teams battling to destroy the opposing Ancient, and its live tournaments are known for loud, partisan crowds. Short crowd reactions from those broadcasts are widely reused online because they instantly signal a big competitive moment without needing commentary or context. Editors favour this kind of clip for gaming videos, streams and memes, where a few seconds of cheering can turn an ordinary play into a shared celebration.
