What the word "Sixpounder" means

Thaks for your help, this is the complete sentece.:

Well let me see what you're trying to do
You're turning me on for you to use
The breaking voice getting nearer
Trying to be something that you're not

Well let me tell you about you
I'll stop the pain, alright...
Well I'll refuse to bring you down
I'll be smart, resist you... GO GO!
WAR!

I refuse to be brought down by you
Praise is far away from what you know
Not only are you crankin' up my rage
I am ready to blow you away!
666! (Pounder)

(Solo)

It's not the same another time, that time will never end
And I'll refuse to wait for you
When you're trying to persuade me back... Hey! Go!
Love the Sixpounder!

(Solo)

Let me see what you're trying to do
You're turning me on for you to use
Well I refuse to wait you out
I'll be smart, resist you... GO GO!

WAR! WAR!
Well I refuse to be brought down by you
Praise is far away from what you know
Not only are you crankin' up my rage
I am ready to blow you away!
666!
