How would I say "knuckleheaded"? It is the adjective of "knucklehead" and, in the context in which I want to use it, means "inept", except much stronger, really implying that the person has bone where his brains should be. What I precisely want to say, to a poorly informed person who pulled rank to override a decision is: "Your knuckleheaded intervention has just fucked everything up ten times more than they were already fucked up."
