This clip circulates online as a short fan-made sports reaction sound tied to Boston Red Sox baseball, specifically to the moment a pitcher records a strikeout. Rather than coming from a single famous broadcast, it works as a piece of crowd cheering that fans reuse in edits, memes and game recaps to mark a big out. Its brevity is part of its appeal, since a one-second chant can be dropped into a highlight without interrupting play-by-play, and it still signals Red Sox pride to anyone who recognises the team.
