blunderhead

One who bungles

A blunderhead is a person prone to blunders—someone habitually clumsy or foolish in their actions or judgments.

The word is old-fashioned and mildly insulting, carrying less sting than harsher terms for stupidity: Don't be such a blunderhead; you've got the map upside down.
