This sound is widely recognized as a quest completion notification from The Witcher games, especially by players who know the RPG interface and progression cues. Short reward sounds like this spread easily in clips because they communicate success in under a second. Online, it is often used in gaming montages, stream highlights and ironic edits where a very ordinary task is framed like a major fantasy accomplishment. Its staying power comes from that instant sense of completion and the strong association with role-playing game progress.
