What is Gwen saying?

Ever since I saw her sing on SNL, my curiosity has been killing me. What are the words to that "Holla Back" song? What's she saying? Now I know and now you'll know, too:

"Uh huh, this my shit
All the girls stomp your feet like this

A few times I've been around that track
So it's not just goin' to happen like that
'Cause I ain't no hollaback girl
I ain't no hollaback girl
[2x]

Oooh, this my shit, this my shit [4x]

I heard that you were talking shit
And you didn't think that I would hear it
People hear you talking like that, getting everybody fired up
So I'm ready to attack, gonna lead the pack
Gonna get a touchdown, gonna take you out
That's right, put your pom-poms down, getting everybody fired up

few times I've been around that track
So it's not just goin' to happen like that
'Cause I ain't no hollaback girl
I ain't no hollaback girl
[2x]

Oooh, this my shit, this my shit [4x]

So that's right dude, meet me at the bleachers
No principals, no student-teachers
Both of us wanna be the winner, but there can only be one
So I'm gonna fight, gonna give it my all
Gonna make you fall, gonna sock it to you
That's right, I'm the last one standing, another one bites the dust

few times I've been around that track
So it's not just goin' to happen like that
'Cause I ain't no hollaback girl
I ain't no hollaback girl
[2x]

Oooh, this my shit, this my shit [4x]

Let me hear you say, the shit is bananas
B-A-N-A-N-A-S

the shit is bananas
B-A-N-A-N-A-S
[3x]

few times I've been around that track
so it's not jus ganna happen like that'Cause I ain't no hollaback girl
I ain't no hollaback girl
[2x]

Oooh, this my shit, this my shit [4x]"

Not that it means much. I guess Gwen is saying that she thinks cheerleaders are slutty and like to gossip. Nothing revolutionary.
