No clear source, character, or original recording is known for this sound, which appears as a user uploaded clip with a keyboard smash style title. Sounds like this spread because the title itself looks like frantic typing, a common way people write screaming, laughing, or panicking online. The extended length sets it apart from short reaction clips, so creators usually trim a favourite section rather than use the whole file. It remains in use as an intentionally meaningless reaction for moments that are too chaotic for real words.
