Similar to the grammar nazi the convo nazi is found of sites such as facebook, the convo nazi is usually the person who status the converstaion is on. They will tell people to: only talk about things related to the staus, not to talk about a certain subject or not let people even talk (sometimes going so far as to delete the comment)
