The act of doing one thing and not the other; One who accepts the worse and complains about the best, a backwards thinker, a walking paradox, completing a task and leaving out the most important part, doing something totally backwards, ignoring priorities of major importance and acknowledging the minor.

Used to describe someone who is outwardly picky and meticulous about everything, but seems to be unaware of what's nasty about themselves at the same time.
