Someone that is so thick skulled that you couldn't pound an intelligent idea into thier head with a hammer. A person with no clue how to function in society & therefore is a nuisance to everyone. Boundless incompetence. This word is believed to be derived from the term hilljack.
That polejack acts so backwoods, he makes a hilljack seem citified.
