Talking Out Your Ass-
It's when someone begins to speak or writing on face book before they know the truth, irregardless how it might make others feel. Sometimes when the truth is then explained to them, they twist what you say and speak even louder out the same orifice. We are all susceptible to this terrible condition wether we admit it or not and If left untreated it can lead to a complete break down in communication, alienation, loneliness, severe depression, and anxiety which worsens the condition. But if caught in time can be treated properly with truth and logic can be completely avoided and leave practically no ill side effects. Even with proper treatment occasional flare-ups should be expected. Laughter is also always a good antidote.
