Choo choo, ahh, beep beep
Choo choo, ahh, beep beep

Bad girls
(Bad girls)
Talking about the sad girls
(Sad girls)
Sad girls
(Sad girls)
Talking about bad girls, yeah
(Bad girls)

See them out on the streets at night
(Walkin')
Picking up on all kinds of strangers
(If the price is right)
Well, you can't score
(If your pocket's tight)
But you want a good time

You ask yourself who they are
Like everybody else
They come from near and far, oh yeah

Bad girls, sad girls, you such a dirty bad girl
(Beep beep, uh-huh)
You bad girl, you sad girl, you're such a dirty bad girl
(Beep beep, uh-huh)

Now you and me we're both the same
(Both the same)
But you call yourself by different names
(Different names)
Now your mama won't like it when she finds out
(Finds out)
That her girl is out at night

You ask yourself who they are
Like everybody else
They wanna be a star, yeah

Bad girls, sad girls, you such a dirty bad girl
(Beep beep, uh-huh)
You bad girl, you sad girl, you're such a dirty bad girl
(Beep beep, uh-huh)
