(Pop) ahh
If it pops into my head
It's comin' straight out my mouth
If you ain't treatin' me right
It's somethin' 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
Oh! If I got something to say
Oh! If I ain't gettin' my way
Oh! If it's important to me
I'll stand up n 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
'Cuz 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
Some people go with the crowd
They never say what they think
They don't wanna rock the boat
'Cuz they're afraid it'll sink
But I can't sit on my hands
When I know somethin' ain't right
'Cuz when ya bottle up it up baby
It'll eat you alive
Oh! If I got something to say
Oh! If I ain't gettin' my way
Oh! If it's important to me
I'll stand up n 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
'Cuz 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
[Outro]
Haven't you ever wished, you could go back in time
And do somethin' 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 comin' straight out my mouth
If you ain't treatin' me right, right, right, right
I'll stand up n scream to get what I want
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 n sing aloud
'Cuz 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
