This sound comes from Discord's in-app notification system and became widely reused in meme edits, gaming clips, and chat-based skits as Discord grew popular with online communities in the late 2010s and 2020s. Creators use it as shorthand for a new DM, server ping, or awkward interruption without needing any explanation on screen. Its staying power comes from how instantly recognizable it is to regular users and how well a single short ping fits fast pacing, captions, and fake message overlays.
