Get the formerly-known-as mug.
A person who is known for being wrong about everything that is worth having an opinion about.

If you have a plan you want to follow you should ask their opinion about the plan. If they hate it, then you should probably go ahead and implement the plan. If they love it, then you need to go back to the drawing board as your plan will have deficiencies that you haven't been able to see, but the Known Idiot will have detected and loved.
Programmer 1: John is our known idiot, can you ask him what he thinks of your software design before implementing it?
Programmer 2: I asked him already - he thought it was a great idea....so I'll throw that design away and start again, it's obviously full of bugs.

This means LISTEN UP MF'ER! Youre about to hear something important and you WILL be held accountable for the info. It's accompanied at times by ringing in the ears, headache , and blurred vision. A LET IT BE KNOWN can be in verbal or written form.
They are usually ineffective because the non-listeners are often dumbasses but they are still accountable for the info.
Dr Phil--Dod you tell Gregor about his ass?
Krystola- ahhh, Imma wait and beat his ass when he gets outta jail!
