The title comes from a user generated soundboard upload where the second half is a random string of letters, typical of a keyboard smash typed in frustration or amusement. Clips like this spread through short reaction edits and chat style memes, where nonsense text becomes a shorthand for being speechless. It has stayed in use because it needs no context from a film, song or show to work, anyone who has seen a garbled message online understands the reaction immediately and can reuse it in new situations.
