Listed simply as rX outro, this clip circulates on soundboards as a generic closing sound rather than a documented quote or song excerpt. Its appeal comes from its length and function, at just over two seconds it is long enough to register as an ending but short enough to reuse across many videos. Editors share it for outros, end screens and stream highlights, where a consistent sign off helps viewers recognise a creator's style. It remains in use because it solves a simple editing need without dialogue or lyrics.
