Username Question help

[xXSaberWolfXx]

So, I'm a girl, and I play MW3 (modern warfare 3). I am thinking of going on multiplayer, but the problem is, I can't find a good username for myself.
Here's some info about me to make it easier to answer:
Gender: Female
Favorite Gun: I abosolutely LOVE snipers, but I like knifing too.
Favorite color: electric blue
Favorite animal: wolves
Idea of my username: I want it to sorta say that I'm a girl (nothing TOO girly please) Maybe with a "gurl" in it? But i want to be known as a girl who beat the boys at MW3
So yeah. Any ideas?
I like names such as: Silver, Storm, SnapDragon, Saber, Ghost..ect.
