This sound comes from World of Warcraft, where it plays when a character gains a level. The cue became widely recognized through years of gameplay videos, machinima, livestreams and gaming memes. Online, creators use it far beyond the game itself because the meaning is instantly clear: progress, reward and a new tier reached. That simple, universal idea keeps the clip popular in short edits, especially when someone improves suddenly or completes a challenge after repeated failed attempts.
