A "paper tiger" is someone or something that seems powerful or threatening on the surface, but is actually weak and ineffective. It's all show and no substance, like a ferocious-looking drawing that can't actually bite. Think of it as a hollow threat, a bluff called out. It might roar loudly, but it lacks real power to back it up. It’s basically all bark and no bite, a facade of strength covering up vulnerability. Imagine a bully who talks tough but crumbles when challenged; that's a paper tiger!
