I think most men know that there are phrases that can be said in a locker room that wouldn't endear you to the average women, but that doesn't really reflect on women at all.

There are certainly always exceptions, but unless you're a fairly tame guy or friends with fairly non-typical women, locker-room talk usually won't go over well.

My comment wasn't in anyway meant to be demeaning to women.

In the US, perhaps. Maybe the ladies are just courser here in Europe but get a few of them together and they're usually coming out with language that'd make me blush.

Mind the generation gap as well... as both men and women get older, language tends to civilize.

In the upper middle classes and above, perhaps. In the working class, my personal experience is the old are just as foul mouthed as the young (although they tend to use it in the correct company, rather than everyplace). This might sound classist, but I'm working class and it's what I've experienced in any case.
