A fractious person is bad enough, but to be way too fractious requires many years of persistent practice.

fractious: tending to be troublesome, quarrelsome, irritable, refractory.

refractory: resisting control or authority, stubborn, resistant to treatment or cure, unresponsive to stimulus (threats or rewards).

These are the defining characteristics of curmudgeonhood, my ultimate goal.
