This sound comes from Discord's interface audio and is widely recognized as the tone for leaving a voice call or channel. It spread through meme edits, gaming clips and reaction videos because the cue is so fast and easy to understand. Online, it often stands in for social rejection, abrupt exits or a joke dying mid-conversation. Its staying power comes from how many viewers already know the sound from daily use, much like the windows xp shutdown cue is recognized beyond its original context.
