Noun. Someone who uses large fonts, hackneyed arguments, bad logic, and an air of superiority to make up for his total lack of friends. Furthermore, this type of person is only enjoyed by those who have an IQ lower than his or her own. Consequently, the only company that a "jawknee" usually has is a single cancerous ferret.
So and so proved themselves to be an incontrovertible jawknee with an incredible display of incoherent, anal retentive intellectual debauchery that transcended anything previously witnessed in the history of mankind.
Probably one of the most overratted, underachieveing, over-payed players in the NBA. And of course, the Knicks salavate over guys like this. I have never heard the word "potential" used so much on a player before. He will never, ever live up to his "pontential."
Fan 1: man that guy is doggin it out there... it looks like he should be dominating everyone that guards him.
Fan 2: Yea, he's really pullin a Tim Thomas right now.
