A grunting state of agitated displeasure assumed by egocentric engineer or sports types who are quite fond of getting their own way, by brain or by brawn, and find themselves powerless to get what they want. It is generally saved to manipulate lesser minds into capitulating to their will. Those who challenge them find this tactic pointless and extremely amusing.

“If I don’t get _________________ by five tonight, I am going to be extremely disgruntled.”

I know you know this, but maybe you don't KNOW it know it...but ignoring me, or my emails, does NOT make things go away as if they never happened. It only serves to make me further disgruntled and unhappy.”
