This sound is commonly used online as a generic call ended effect rather than a clip tied to one famous scene or character. Short hang up tones spread across meme edits, prank audios, gaming clips and vertical video because they communicate instant rejection with almost no setup. Creators keep using it because the meaning is obvious: the conversation is over. Its usefulness comes from how quickly viewers understand the cue, especially when paired with a hard cut, freeze frame or deadpan reaction.
