A serious disease which, once it has control of a person, causes them to spew forth incoherent babble from the bowels of the voicebox. Often extremely frustrating for the victim and extremely hilarious for the observer.

Compliments to Eric :-) for the examples

"It's 90% perception! Shut up, shut up, shut up!"

<yells> "I need to know EXACTLY where your hands are!" ... "I mean the general... area..." <falls over, asleep>

Somebody who doesn't know how to shut up. They love the sound of their own voices and continue to drone on and on repeating the same ponits over and over again in different ways before they wrap up what they're saying. People with verbal diarrhea can take a simple yes or no answer and make it last for several minutes.

Prime examples of those who suffer from the disorder are politicians and managers.
"Do you plan to increase the price of eggs?" (Simple yes or no response required)

"Well taking into account the inflation rate and current market trends we can make several assumptions, first and foremost the costs to farmers have increased over the years due to increase in the price of chicken feed taxes and the like. These prices increases at the bottom end of the chain will no doubt be reflected further up the chain but we are doing all we can to keep the price static."

"Could you give us an answer without the verbal diarrhea?"
