This clip circulates online as a reaction sound rather than a line tied to a widely recognised film, show or song, and its appeal comes from how instantly readable it is. The drawn-out fahhh followed by get out works as a universal dismissal that needs no context, which is why creators reuse it for gaming clips, reaction videos and short-form edits. Its two-second length also helps: it fits neatly into a cut, a transition or the end of a joke, so it keeps travelling between soundboards and social videos as a quick way to say someone has overstayed their welcome.
