Draymond Green is Mocked By Team USA Over Penis Pic

You post penis pics online -- you get mocked by your teammates ... even if you're on Team USA.

Draymond Green got some razzing at practice Monday ... courtesy of his superstar teammates like Boogie Cousins and Klay Thompson.

Green was giving an interview when his teammates were discussing the situation ... and shouting some stuff at Draymond to give him a hard time.

The best part -- when Boogie pretends to hold a mic in his hand and says, "Does this remind you of anything?"

You gotta watch the clip.
