Dirk Nowitzki takes uppercut to balls from Shaun Livingston (VIDEO)

When Shaun Livingston ran up against a slightly taller Dirk Nowitzki in the post Saturday night, the Warriors defender did something he should not have done.

Livingston was charged with a flagrant foul after turning Nowitzki's boys into a couple of speedbags with a well-placed uppercut.

And as you can see in the video below, the Mavericks star wasn't happy about getting "Dirked."

Surprisingly, Livingston wasn't ejected for the intentional groin-shot.
