Identify and describe curley

Curley has a major case of "small guy complex". He feels so worthless about himself that his posture around others is always offensive. He tries so hard to look tough, like a guy not to be messed with. He constantly needs to prove to others and himself that he is of "manly" worth. Ironically the other men in the ranch stay away from him but only because Curly s the boss's son.
