Alice tells Bob to shut up and he hasn't even said anything. However, she just knows that Bob's about to offer an opinion—or at least that he would be justified in doing so. This is often used to lampshade Hypocritical Humor or Blatant Lies, or to forestall the obvious answer when Alice has walked into a Double Entendre or Rhetorical Question Blunder.
