If it pops into my head
It's coming straight out my mouth
If you ain't treating 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

(Oh) if I got something to say
(Oh) if I ain't getting my way
(Oh) if that's important to me

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 and say it loud
'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

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 you bottle it up, baby
It will eat you alive

(Oh) if I got something to say
(Oh) if I ain't getting my way
(Oh) if that's important to me

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 and say it loud
'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

Haven't you ever wished that you could go back in time
And do something different?
Haven't you ever wished you could go back tonight
And 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)

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 and say it loud
'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
