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.
Bo: "Boy, I have a lot of tools in my garage."
Me: "
Hang up the phone,
tubby."
