There is no documented single source for this short phrase, so it is best understood as an internet reaction clip rather than a line tied to one show, film or creator. Its appeal comes from its plain wording, which works without context whenever someone is overstaying a live broadcast, a call or a conversation. Short reaction sounds travel well because they can be dropped into edits, streams and group chats without explanation, and this one has kept a following among creators who like direct, confrontational humour. Its bluntness is the point, making it reusable whenever a moment needs an ending.
