1. He repeatedly mentions his nice guy status at every possible chance either online, via texts, or face-to-face or all three.

2. He gets upset and defensive if someone questions his nice guy status and his current behavior. Usually by bringing the converstation back to the accuser in a vicous way.

3. He talks about girls politely, then talks about them in a very scandelous way.

4. He is a closet man whore or player.

5. He is a closet douchebag.

6. He believes that he is more righteous or of better moral standings than the rest of his friends and the world.

7. Is an avid worshipper and watcher of Jersey Shore and takes notes hoping that one day he will be the next Situation. (Not Vinny or DJ Pauly D that would be just regular douchebag behavior).
