Rehab - Deal With Me (Him & Her) lyrics

I tried to be cool, I tried to maintain
Let you sit up in my head
And rent space in my brain
I chilled to keep from bashin'
Car windows and crashin'
That's why you see me dashin'
I hate to be lashin' out of fashion
Besides I'd rather let it ride and
Take a cop car ride
I'm afraid of me, that's why I hide
But those days are done
I'm gettin' what I want and
I don't need a gun
A lot of people gonna run the race
But, I'ma be the one that
One up to mushroom cloud
It's about what you say not how loud
I've dealt with you, now deal
With me, standin' on top, see see see

If I say something to piss you off
Or if the sight of me makes you wanna barf
It just may be that you can see
A little bit of you in me

Cuz I've been runnin from this and that
And those and them and him and her and
I'm not sure exactly what I'm gonna do but I
Gotta make a decision this time

I woulda never though, I got what I sought
Did a lot of dumb shit
But I ain't get caught
Pants still saggin', back on the wagon
Came back with a bloody nose
Bleedin' and braggin'
I know you hoped I fell off
I know if you could, my organs you'd sell off
But, it's cool, I ain't no fool, and nah
I can't let you push in my stool
So when you see me say "Hi!"
We can hang for a minute
But after that bye bye
Hit me on the 2-way for a three way
And maybe I might pull off the freeway

So you say I'm a piece of shit
How 'bout you motherfuckin suck my dick
Cuz it just may be that you can see
A little bit of you in me

Cuz I've been runnin from this and that
And those and them and him and her and
I'm not sure exactly what I'm gonna do but I
Gotta make a decision this time
I'm my own ball and chain and all the blame
Always comes right back on me
I've lived with y'all for long enough
Proved I'm tough now
Y'all gotta live with me

What is the meaning of this?
Where did buzzer come from?

That's the metal detector concealed
In the doorway sir
I'm afraid you're carrying some
Large metal object and
I'm going to have to search you if you don't

I certainly do mind
I'm a Brigadier General in
The United States Army
With and important appointment

Cuz I've been runnin from this and that
And those and them and him and her and
I'm not sure exactly what I'm gonna do but I
Gotta make a decision this time
I'm my own ball and chain and all the blame
Always comes right back on me
I've lived with y'all for long enough
Proved I'm tough now
Y'all gotta live with me

You are in another universe where
The dominating force is sound

Y'all gotta live with me

But that sound in my head sent
Me flying in the other direction

Ha ha hahah

Y'all gotta live with me
