Here are some moves that will spark the crowd and stun your friends.  These moves are for the more advanced players.

Back Spin

Start with the ball in your left hand.  Dribble behind your back and as soon as the ball touches your right hand, you break into a spin move.  The defender should be out of place now, and you can drain a 3 ball or drive it in.

Spider

Stand with your legs spread apart and then drop the ball in front of you.  Now hit it with your right hand and then your left hand.  When you hit it with your left hand, push the ball through your legs behind you to your right hand, which should be behind your back now.  Then reach behind you and hit it with your right hand and then left hand.  When you hit it with your left hand push the ball through your legs in front of you to your right hand, which should be back to the front now.  Then reach in front of you again and hit with your right hand and then left hand and keep repeating.  This is a move that must be practiced and perfected before doing it in a game.

Spin Back

Start your dribble in your right hand.  Start a spin move but stop half way so that your back is to the defender.  Now dribble the ball behind your back from your left to your right.  Now do what you please.
