This sound is widely associated with legendary loot drops in Diablo, especially the modern action RPG entries that made item rarity cues a big part of the experience. Online, the clip spread beyond gameplay into edits, reaction videos and streamer highlights because it instantly communicates rarity and reward. Even outside Diablo, people use it as shorthand for finding something valuable, getting an upgrade or landing a surprisingly good result. Its staying power comes from how quickly the cue tells the audience that a jackpot moment just happened.
