The ending call sound is a generic telephone hang-up effect rather than a clip from a specific show, film, or viral moment, which is why it appears in so many different kinds of online video. Creators use it as a shorthand for a conversation being cut short, borrowing the familiar sound of a real phone call ending to make a scene feel immediate and relatable. Because almost everyone recognises that click and tone, it still works across pranks, skits, reaction videos, and edits where a quick, unmistakable ending is needed.
