A person, friend, family member that plays any Call of Duty game 24/7 with only bathroom breaks. You can also hear them yelling through the wall at 3:00am and later. They are always angry if they aren't playing and usually have no friends in real life.
Me: My brother is a COD whore 24/7 and he never shuts up.
Bob: Yea, I hate those people, they have no life.
