numpty 

A person who is incapable of performing the simplest of task correctly. Usual symptoms include poor hand-eye coordination, zero common sense and the general illusion that they are special (caused by parents referring to them as such and the numpty not fully grasping the meaning implied).

Common causes are being dropped as a baby or repeated heavy blows to head in later life.
