Multiple Username Disorder: A condition that compels those inflicted to create a multitude of aliases on websites such as 'IMDb', in order to praise or defend their own message-board posts -- the ultimate goal being to elevate these aliases to becoming the board leaders, and thereby controlling all topics of discussion. Often, the MUD sufferer will create lengthy message-board threads, in which the posts are entirely by his/her imaginary correspondents.
