Discord launched in 2015 as a voice and text platform for gaming communities, and its incoming call tone quickly became one of its most recognizable audio cues. As streamers, YouTubers, and TikTok creators began recording their screens and reactions, the ringtone traveled beyond the app itself, appearing in pranks, skits, and reaction edits where a sudden call drives the joke. It remains popular because almost anyone who games or chats online recognizes it instantly, so a few seconds of ringing can set up a call without any explanation.
