[Verse 1]
I won't apologize for speaking my mind
Won't be ashamed for having a good, good time
I'm not sorry for the way that I shine
'Cause life's too short, l-l-l-life's too short to hide
Hey!

[Chorus]
I'm such a big mouth and I know what I'm talking about
My hands on my hips with so much confidence
Got a lot to say to you
I'm such a big mouth and I know what you're all about
You're so scared of my sass, all my smarts, all my class
Boy you got some work to do
La la la la la la la la la
Big mouth coming through

[Verse 2]
Who are you to say what I should do with my body
Last time I checked I don't belong to nobody, oh
[?] I won't sit here in silence
I fight for respect
Won't take nothing less [?]

[Chorus]
I'm such a big mouth and I know what I'm talking about
My hands on my hips with so much confidence
Got a lot to say to you
I'm such a big mouth and I know what you're all about
You're so scared of my sass, all my smarts, all my class
Boy you got some work to do
La la la la la la la la la
Big mouth coming through
[Bridge]
Don't got nothing to prove
I don't answer to you
I won't hold my tongue for no one
I'll be ready to shoot
Try me you're going to lose, hey

[Chorus]
Big mouth! (yeah yeah yeah yeah!)
And I know what I'm talking about
My hands on my hips with so much confidence
Got a lot to say to you
I'm such a big mouth and I know what you're all about
You're so scared of my sass, all my smarts, all my class
Boy you got some work to do
La la la la la la la la la
Big mouth coming through
