The exact source for this Arnold scream is not clearly confirmed from the available details, but it is circulated online as a short movie-style reaction clip. Sounds like this spread through soundboards, meme compilations and quick edit apps because they deliver instant drama in under ten seconds. It remains useful because the emotion is obvious even without context: viewers immediately read it as panic, pain or total overreaction, which makes it easy to layer onto fails, fake scares and exaggerated reaction posts.
