angryvating
A situation that is profoundly aggravating and, because of an inability to impact on it in any significant way, one becomes very angry. So the situation is angryvating.
After having tried multiple times to explain the problem to the computer help desk customer service representatives who just didn't understand United States English, he finally slammed down the phone and got a beer while telling his buddy that he had the most angryvating afternoon trying to get some help. And his computer still wasn't working. ARRRGGGH! How angryvating.
