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 JackBall just sitting there on his fat ass. I bet he took Jack Ball lessons from Cait.
Telling someone what they want to hear to get what you want. Boosting someone's ego to get what you want from them. Making them feelspecial about themselves.
I'm about to Jackball this guy,boost his ego a little bit, to get what I want.
