When any ones mouth runs like diarrhea with useless crap.
Just listen to G.W.Bush verbal vomit @ next available opportunity.
Words strung together to make one either sound stupid or make no sense.
When a person says whatever comes to mind without thinking them through, specially when drunk.
Telling your boss he smells like a turd covered in rotten bananas at the Christmas party after having a few drinks, is a case of "verbal vomit"
