Little is known about who first made this clip, and its vague name suggests it was passed around as a loose MP3 file rather than taken from a named show or film. Text to speech voices became a staple of meme editing because anyone could generate them, and short, context free lines like this one were shared on soundboards and in chats as reaction sounds. Its appeal is that it fits almost any awkward exchange, so creators keep reusing it whenever a human reply would feel too normal.
