"Blue murder" is an idiom that means to scream or shout very loudly, often in protest or distress. It implies a great deal of noise and commotion. Think of it as raising a huge fuss or creating a major scene. Unlike a polite request, shouting 'blue murder' demands immediate attention. It's an exaggerated expression, suggesting a level of outrage or panic. It's like the verbal equivalent of a dramatic tantrum. π
