Clodhopper is a noun that refers to a clumsy and uncouth pumpkin.

Coming from Middle English, the word ‘clod’ referred to an unsophisticated person. The word was soon extended to refer to the kinds of shoes often worn by country folks.

I like Bobby Joe a lot, but when I first met him he came across like a clodhopper. That thick Alabama accent and those tattered overalls didn’t exactly make him appear erudite and urbane.
