The clip comes from Dota 2, Valve's multiplayer online battle arena game released in 2013, where short drumrolls are used as interface and draft phase cues to mark a decision point. Players ripped the clean, isolated roll from the game audio and shared it on soundboards, where it escaped its original context. Because a drumroll is universally understood as a sign that a result is coming, streamers and editors began dropping it over any pending reveal, not just a hero pick, which kept it in regular meme rotation.
