A person, who usually isn't very intelligent, who will not shut up. It's typically a cover for their own inferiority.

When someone won't STFU, and he doesn't realize that everyone stopped listening a long time ago.
Aerofan thinks he sounds intelligent by padding his speech with a ton of words. But we know the truth. He's only compensating for his small penis. He has diarrhea of the mouth. SHUT UP!

1. a condition where some obnoxious bozos are always throwing their weight around and belittling all those who don't agree with them. Such people think they "know it all" about everything when they really know zero because everything they say is a load of crap.

2. a similar condition where someone cusses way too much because he/she thinks it's "cool" but it really makes said person look like a stupid juvenile fool.
1. today in this age we are swamped by a lot of people who have diarrhea of the mouth.

For example, certain politicians wasted time and money holding sessions geared strictly to determine if an opposing party should be labeled as "socialist". They don't even know what socialism is, and there's too many problems that require remedial action NOW. These dunderheads got a case of petty stupidity. There's no time for it now.

2. On an ICP album and one by Limp Bizkit there are songs that actually tell you how many times they use the word "fuck". It's over 80 times each! Now that's a case of major diarrhea of the mouth.

3. Lee is watching TV and an ad for some airline is on. The host just keeps on blabbing on and on. He's offering reduced air travel rates only IF Lee schedules his flight on certain times of day, on certain days of the week, using a certain credit card, showing proof of ownership of a new Subaru car and he must've kissed Marilyn Monroe. So many conditions! Lee thinks that the ad host has diarrhea of the mouth - all he's saying is total SHIT.

4. Kid Rock should be renamed Kid Ego. He's got absolute diarrhea of the mouth.
