A klutz is a person who is clumsy, foolish, inept, or accient-prone. The term is perhaps derived from the Yiddish קלאָץ klots ('wooden beam'), cognate with the German Klotz, meaning a "block" or "lump". The British slang, pillock and the Australian slang, galah are used with similar meaning, particularly in terms of being foolish and inept.
