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.
