This sound is widely used online as a short celebration reaction rather than being tied to one clearly identifiable source in the provided details. Creators drop a drawn-out “let’s go” over gaming wins, sports highlights, meme edits, and videos where a payoff finally arrives.

It often appears alongside other hype reactions such as We Are The Champions in victory edits.
