A derogatory term used to describe an individual, usually female, who exhibits two or more of the following characteristics at any given time;
-Infinitely huge superiority complex
-Inability to distinguish between opinion and fact
-The assumption that everyone *else* is overreacting, when the opposite is true
dislike towards patriotism
-Inability to take responsibility for one's own actions
-The assumption that constant whining does not in any way constitute "taking things seriously"
-The assumption that talking being someone's back is okay unless it's about oneself
This term originated on a relatively obscure video game forum as the screen name of a particularly unpleasant member hated by the majority for the reasons given above, and has since leaked out on the internet to become a fairly offensive insult.
It can be used as either an adjective or a noun.
