An annoyed or embarrassed response to the stupidity or incompetence of another. Synonymous with "Shut the fuck up", or "Jesus, you're stupid". Derived from one man's inability to counteract the obliviousness of those around him, to which he blurted it out in frustration. Also, an appropriate reply to an unfunny or otherwise retarded joke.
