2.
Someone who loves to give advice when not playing. A "back seat" halo player. Complains excessively about shot guns and bubble shields cause they still play halo 3. Says early and often that they would never use "noob" weapons but was caught with camo and a shotty. If the sword is down, halo god will respond. They do not call themselves the Halo God, you and friends do behind their back in a derogatory fashion, but be careful if they find out your calling them that they may unknowingly take it as a compliment.
Mit: "To your left, on the right, over there, shoot! shoot! Noob weapon. "
Marc: "Dude, just let me play."

'Later'

Natty: "Halo God was annoying today"
Marc: "Its terrible. He thinks he's so good. Atleast now he's getting shit faced on mikes hard lemonade. Thank god he's gone."
