Dimebag Darrell Level Insanity is a term that originates from Age of Empries: a Refreshed Map Game.
The game became increasingly ASB and people began doing silly things to the map. Soon Zacoftheaxes came and added a picture of Pantera guitarist Dimebag Darrell to the map Between China and Russia. This soon became a term to tell when a map game has gone so insane it would be normal for Dimebag Darrel to appear on the map. The term itself was coined by johngalt when Age of Empries: a Refreshed Map Game was going towards this level again.
