[Verse 1]
If it pops into my head
It's coming straight out my mouth
If you ain't treatin' me right
It's something you'll hear about
I can't be little "Miss Sunshine"
All of the time
If you want a piece of my heart
You'll get a piece of my mind

[Pre-Chorus]
Oh
If I got something to say
Oh
If I ain't gettin' my way
Oh
If it's important to me

[Chorus]
I stand up and scream
To get what I need
I got a big mouth
I got a big mouth
Don't care what you think
I don't give a beep
As long as you listen to me
When I turn it up n' sing aloud
'Cause I'm not afraid
To give you a taste
Without the sugarcoat, babe
What can I say?
The words just come out
I got a big mouth
[Verse 2]
Some people go with the crowd
They never say what they think
They don't wanna rock the boat
'Cause they're afraid it'll sink
But I can't sit on my hands
When I know something ain't right
'Cause when ya bottle up, baby
It'll eat you alive

[Pre-Chorus]
Oh
If I got something to say
Oh
If I ain't gettin' my way
Oh
If it's important to me

[Chorus]
I stand up and scream
To get what I need
I got a big mouth
I got a big mouth
Don't care what you think
I don't give a beep
As long as you listen to me
When I turn it up n' sing aloud
'Cause I'm not afraid
To give you a taste
Without the sugarcoat, babe
What can I say?
The words just come out
I got a big mouth
[Bridge]
Haven't you ever wished
You could go back in time
And do something different?
Haven't you ever wished
You could go back tonight
Say what you really meant
Say what you really meant?
If it pops into my head
It's coming straight out my mouth
If you ain't treating me right, right, right, right

[Chorus]
I'll stand up and scream
To get what I need
I got a big mouth
I got a big mouth
Don't care what you think
I don't give a beep
As long as you listen to me (As long as you listen to me)
When I turn it up and sing aloud
'Cause I'm not afraid (I'm not afraid)
To give you a taste
Without the sugarcoat, babe
What can I say? (What can I say?)
The words just come out
I got a big mouth
