Ideas for aim sn?

i made a myspace, email, and aim sn over the summer. all three are the same and are after school i go to. im going to a different school next year so thats why i want to change it. I can be blonde, ppl think im preppy, im outgoing and talkative. i love to laugh and smile. i really want something different and something that describes me. my name is megan. does anyone have any ideas?
