In this part of West Virginia, a hob gobbler is what people call a single male turkey that is either staring at you or acting in another eerie way. It is believed to bring bad luck in the same way as a black cat, although people don't take the bad luck aspect very seriously.
Sometimes hob gobbler is also used teasingly to describe someone who is acting like a misanthrope or loner.
"Oh lord, is that a hob gobbler over there at the edge of the bushes?" "Nah, see those two hens in the trees? He's probably just showing off for the ladies."
