Idaho Spud
1. A backwards resident of the state of Idaho, which is known for producing potatoes, i.e., the famous "Idaho Spud."

2.)A candy bar comprised of chocolate flavored marshmallow covered in chocolate and coconut sprinkles, which superficially resembles a potato.
He was an Idaho Spud, to be sure, right down the grimy baseball hat emblazoned with the John Deere logo, and believe it or not, he was buying an entire box of Idaho Spuds. Which might explain the black stumps of his teeth.
