Yes, I am aware. But then again I phrased my original statement to show that there was a small frequency of use of these terms. Where females (in my area) have a very high frequency of referring to each other as girls. Almost like "woman" is a formal term.

That's anecdotal at best. These are colloquialisms, they've been around well before you and I were born.

Yes.

I'll gladly refer to myself as a girl, but I only ever use "woman" in formal contexts.
