And the funny thing is, it's mostly colloquialisms anyway. My female friends and I use "ladies" among ourselves (some use "gals" or call each other "doll" or "chick" once in a while). There's an email thread among us with the subject of "Girls' Night Out" right now.
So... I don't know. The words we use change depending on what location we're in, what generation we're from, what group of people we're in, etc. "Gals" sounds funny to me, personally, so that's why *I* won't use it. I'd rather just go with the flow and use the words people are comfortable with, since they aren't personally important enough to me (in this case) for me to weigh in heavily either way.
