The clip circulates online as a short, shareable reaction sound rather than as part of a widely identified song, film or television scene, and its exact original recording is not clearly documented in the listing. Its appeal comes from the phrase itself, which has travelled through memes, reaction edits and short videos where closeness between friends is played for laughs. Because the line is short, easy to recognise and easy to drop into a visual gag, it has stayed useful for creators who want a quick, knowing joke about friends who are never apart.
