Mr. Noisy takes his name from the Mr. Men character known for being impossibly loud, so a screaming clip under that name spread naturally on meme soundboards as a shorthand for extreme overreaction. Short scream effects have a long history in cartoon comedy, similar to the classic Goofy Yell, where an exaggerated shout sells a fall or fright without dialogue. Online editors keep reusing this version because it is instantly readable, fits almost any shocked reaction, and needs no context to understand why the moment is supposed to be funny.
