1. a very stupid person. Arthur's constant obliviousness of his surroundings and general stupidity made him a perfect example of a clotpole.

Is Clotpole a bad word?

It is actually spelled "clotpoll" and is a very outdated slang term for idiot or dolt (which makes sense, given the context in which it was used.) It also appears to be a variant of the word "clodpoll."

Where did the term Clotpole come from?

a stupid person; blockhead. [1595–1605; clod + poll1]This word is first recorded in the period 1595–1605.
