Dave's note is interesting, but I'm having a hard time putting it together with the words as I remember them. (Note: it's been a long time since I've heard the song and JB's is the only version, so somebody correct me if I'm wrong)

There's a verse that says:

First me go in a room
Take me momma, no, no
Make me lie on a sofa
Make me have-a me labor.

And another:

And I holler "Why?"
repeat X 2
The tortoise boy no wanna me.

I think if it's not about childbirth, WyoWoman's explanation of an abortion runs a real strong second in my way of thinking.

cheers,
