Need New Online Name.?

Im a Girl and I play online games like counter strike and Left 4 Dead on Steam, but i am getting tired of all my annoying friends and i want to start clean. I am having a hard time come up with a new name though. I usually use Roxy just something easy and simple but one of my friends thinks that if i want to start new i need something different and cool. So can anyone help me? Please and Thank You =)
