Discord is a chat and voice platform widely used by gamers, streamers and online communities, and its short notification chime has become one of the most recognisable sounds of online messaging. Because the app runs in the background during streams, gameplay and group chats, viewers began to associate the ding with a new message arriving in real time. Creators then lifted it into edits, memes and reaction videos as shorthand for being pinged, and it remains popular because it is instantly understood without any explanation or on-screen text.
