What deos cocky mean?

Cocky means someone is prideful. Ie is Pike Ladago of Vermont. There was 4 seconds left in the practice and he shot a foul shot but he was so cocky he wallked away, and because of his cockyness, he was cut from the team.

Pike is very cocky, he thinks he's good so he hogs the ball and then turns over the ball to Robert Colluti for a dunk. he also thinks Oklahoma was the 13th colony
