format war

Refers to a repetitive series of hot-headed and destructive actions whereby two or more people seethingly format a computer-disk or other media-storage device over and over to erase the previous user's files because each person either dislikes/disapproves of the content that the other users are storing on it, or each person selfishly/arrogantly feels that his own files are more important/necessary/virtuous than those of any of the device's other users.
