What should my instant messenger screenname be?

I can't think of a new screen name and I want it to involve something about my likes or personality.

What I like - sports, reading (harry potter, eragon and eldest, redwall series, fairest, and other fantasy books), computer, three days grace, linkin...

park, nickelback, naruto, bleach, hikaru no go, japan, ninjas, and shopping.

Personality - funny, kinda mean/rude, gets angry easily, feels alone sad negative, athletic, smart (but I'm a blonde so I always have blonde moments), a good friend, independant (sp?), and caring.

how about..
