"That's the way it's prepared in PA Dutch country. We had it a lot when I was a kid."
That describes the traditional southern "chicken and biscuits" (by the way, there is a reference to it in the stage version of the musical "Hairspray" - it's Edna's craving for this dish that leads her to visit North Ave (a traditionally african-american section of Baltimore), where she sees Tracey). I don't see how it defers in any substantive way from creamed chipped-beef on toast, except that waffles catch more of the gravy.
However, judging by Roscoe's menu (see: http://www.roscoeschickenandwaffles.com/) the Country Boy is fried chicken with a choice of a side (waffle or potato salad or French Fries). The waffle is simply a starch side dish - not all that unlike a biscuit or cornbread (other traditional southern accompaniments to fried chicken).
