Describes a person of either sex who does nothing. Basically contributes absolutely nothing of redeeming quality to the world around them. The word and subsequent definition came about after witnessing a person installing a Jack in the box jack ball on their antenna and asking myself what the hell does that damn thing do? Nothing!
Hey there's Don V doing what he does best, acting like a Jack Ball just sitting there on his fat ass. I bet he took Jack Ball lessons from Cait.
Used to describe anyone sitting on their ass not doing a damn thing, just like a Jack ball you would get from Jack in the box.
"Look at those Jack balls, here we are working and those idiots are playing grab ass"
