I have no qualms with it being used, but I don't particularly like guys talking about chicks as a collective term. That feels a little derogatory, but most other uses of it I'm fine with. When talking about multiple females, I find it funniest for guys to put on a New York gangster style drawl and call them "Molls" or "Dames"
The 50's was where it was at, kids.
Personally, I'd rather not be called a chick, solely for the reason I think dudette sounds funnier, but if someone says "Dude, you have to see this" I won't object.
