Yes I be your baby
Yes I be whatever that you tell me when you ready
Yes I be your girl, forever your lady
You ain't never gotta worry, I'm down for you baby

Best believe that when you need that
Ill provide that you will always have it
I be on deck keep it in check
When you need that I'mma let you have it

Beating my [bad word] like dum di di dey
I love the dirty rhythm you play
I wanna hear you calling my name
Like hey mama mama mama hey mama mama
Beating the [bad word] like dum di di dey
I know you want it in the worst way
I wanna hear you calling my name
Like hey mama mama mama hey mama mama

Yes I do the cooking
Yes I do the cleaning
Yes I keep the nana real sweet for your eating
Yes you be the (boss) yes I be respecting
Whatever that you tell me cause its game you be spitting

Best believe that when you need that
Ill provide that you will always have it
I be on deck keep it in check
When you need that I'mma let you have it

Beating my [bad word] like dum di di dey
I love the dirty rhythm you play
I wanna hear you calling my name
Like hey mama mama mama hey mama mama
Banging the [bad word] like dum di di dey
I know you want it in the worst way
I wanna hear you calling my name
Like hey mama mama mama hey mama mama

So baby when you need that give me a word I be good I be bad for my baby

Make sure that he's getting his share
Make sure that his baby take care
Make sure mama's close on my knees 
Keep him pleased double down
Be a lady and a freak

Beating my [bad word] like dum di di dey
I love the dirty rhythm you play
I wanna hear you calling my name
Like hey mama mama mama hey mama mama
Banging the [bad word] like dum di di dey
I know you want it in the worst way
I wanna hear you calling my name
Like hey mama mama mama hey mama mama
