Kick ass

This isn't a contest, it's more a state of mind.
It's not about violence, it's of a different kind.
It's not about causing pain, it's not about throwing down.
It's a psychological source of inspiration.
Gotta kick ass, I gotta be kick ass.
It's about doing your best, doing the best that you can.
Performance, power, and pride, it's about taking a stand.
You see that girl over there?
She's gonna rise to the task.
Now how would I describe her?
With just two small words: Kick ass.
