Once twice three times you're ladies

How can we know what you've done,
If we can't even do what we are meant to hun,
If it was meant to be,
I wouldn't be heading out to sea!

Once twice three times you're ladies for shame on giving females a bad name.

Once in a twice

-alternative form of "once in a while"
-semi-redneck

Well, only every once in a twice.
