Via google: Girl:

A young or relatively young woman

A young woman of a specified kind or having a specified job - a career girl

Women who mix socially or belong to a particular group, team, or profession - I look forward to having lunch with the girls

Perhaps this is a language issue, but it's just as common for me to call my male friends 'boys' as my female friends 'girls', even though all are adults. Not sure what the issue here is.

If you're calling any female co-workers "girls" in conversations at or about the workplace, you're doing it wrong.

There is a long history of society downplaying women's contributions in the workforce by using cutesy terms like "girls", and some of the definitions you've cited here reflect that. But just because a term like "career girl" was once in wide use doesn't mean that it's still appropriate today. (Or for that matter that it ever was: can you imagine anyone ever having used the term "career boy"?) Much like the ridiculous term "co-ed" for "woman who we decided to allow into college", its time has thankfully come and gone.

I guess the words I use are closer to guys/gals then boys/girls then, except that it's used commonly the language (as opposed to gal in english, which is fairly rare - at least from my experience).

There can be a lot of hang overs in languages that aim to demean and diminish people. Calling a black man "boy", or a woman "girl" is a way to belittle them.

"Boy" vs "Girl" is an interesting one. It's not uncommon, as you pointed out, to call adult women "girl". However you rarely in the straight male world do people refer to adult men as "boy". However in the gay male world, sometimes "boy" is used (e.g. this collection of gay short films 'Boys on Film': http://www.amazon.co.uk/Boys-Film-Hard-Love-DVD/dp/B001L5JMQ... ). This shows that "boy" (and hence "girl") is a slightly sexualised way to talk about someone. Should you be using sexualised terms in a professional environment? No, so say "women".

(BTW: Just because your google search found some results that back up what you say, but might be a bit misogynistic doesn't mean google is right. "Jew Watch" still shows up above the fold if I search for "Jew", but it would be wrong of me to excuse anti-Semitism based on that reasoning)

For men: I'm hanging with the "guys" or "bros." For women: I'm hanging with the "girls." (you can't say "ladies" in this context, you can't use "sisters," you could use "gals" but it would sound like you were from Texas).
