The title references the shrieking string sound famously associated with Alfred Hitchcock’s 1960 film Psycho. Composer Bernard Herrmann scored the shower sequence with forceful, dissonant string gestures that became a lasting shorthand for terror and sudden violence. This clip’s exact recording source is not confirmed, so it is best understood as a Psycho-style horror sting rather than an authenticated excerpt from the film. Similar violin screeches later spread through parody, television, online videos, and reaction edits because audiences recognize the effect immediately.
