Another one For the Femmes: Wouldn't a simple 'Excuse Me' suffice?

Maybe I'm a chauvinist but when did this thing with girls going 'I have to go pee' or variations thereon become hip? Who thinks that's cool!? I really don't need to know exactly which bodily function you're about to carry out, just excuse yourself; 'I'll be back in a minute' or whatever. A little cl for gods sake! Or am I just getting old and not keeping up with things anymore and this is normal?
