incumpetent 

Da state of being brainless and/or naive regarding sperm and its related aspects/properties/effects, such as making a huge mess, implicating someone in a crime, spreading STDs, getting a girl knocked up, etc.

Willie and Monica sure were woefully incumpetent when they carelessly got love-juice on Monnie's dress and thus revealed that there had been some hanky-panky going on between them.

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.

institutionalized incompetence 

When a dysfunctional institution teaches and embraces incompetence as though it is the pinnacle of competence because it is so embedded in its culture.

How does one truthfully explain something like the post office or the prison industrial system to a child without in some way making a reference to institutionalized incompetence?

Buffer of Incompetence 

The person that is worse at their job than you. The person that will be fired if there are layoffs.

Crap... Steven got let go; he was my buffer of incompetence. I'll have to step it up.
