To shadowgirl is the act of joining a public
gaming website and spamming it's forums and shoutbox with false information of yourself in an attempt to gain the attention of
lonely males thus causing an explosion of
drama. In most cases, the shadowgirl is likely an emotionally
disturbed male and feeding it with attention will only fuel the aspie within it. Such false information is but not limited to saying you have a bionic leg after saving your friend, shooting yourself in the arm via ricochet from a soda can, falsely claiming stolen artwork is yours, diagnosing yourself with Multiple Personality Disorder and/or claiming you will kill yourself by drinking large amounts of water.
