Sloppy Knee is when someone's knee is needlessly violating your personal space. Guys who have this notion that their package is bigger than it is usually have Sloppy Knee. This condition happens when people are just too damn oblivious and/or relaxed. Also see; Sloppy Elbow.
I tried to shift into 5th gear but Uncle Charlie's sloppy knee was draped over the center console.
