Oto-incompetentologist

A very long word used to describe an ear doctor that cannot/will not actually perform any mechanical intervention in a patients injured inner ear.

These doctors are often very well paid and drive luxurious sports cars, many moonlight in public hospitals one day a week to obtain state funded indemnity for their private practice with which they quickly return to afterwards (in their sports car) to continue their practice of oto-incompetentologist.

Word sources
otology o·tol·o·gy The branch of medicine that deals with the ear.
(stem of incompetēns) 1590-1600; Late Latin incompetent- unsuitable.

"I had a ringing in my ears and I felt dizzy so I went to the oto-incompetentologist, but he didn't do anything, in fact he did not have a clue what he was talking about and diddled me out of 200 bucks".

Strategic Incompetence 

Purposely performing a task so poorly as to discourage being assigned this task again, but not poorly enough to be fired

Cube Dweller1: Dude, writing the weekly report is a sucky job; how do I get out of it?

Cube Dweller2: Just screw up some people's names and swap some people's tasks, nobody will want you to do it again

Cube Dweller1: Ahh....Strategic Incompetence....a fine idea....my inner slacker is jumping for joy!

Selective incompetence 

Something you "can't" do because you don't want to do it. Something you can get others to do by making believe you can't do it.

When asked to do laundry they put all the white clothes in on hot and then put a brand new red sweatshirt in too. The result was all the white laundry was pink and they were banned from touching the laundry ever again...they could wash laundry but didn't want to so they applied "selective incompetence " to get out of ever being asked again.
