ladies who lunch 

Rich middle-aged women with no jobs or other meaningful way to occupy their time, who descend on upscale cafes around lunchtime to hang out with each other more because they have nothing better to do than because they like the company. Generally despised by cafe workers.

I don't know why Ina Garten has this "ladies who lunch" persona -- you know she busts her ass when she goes to work.

A group of three or more girl friends who compulsively hang out but who barely know or like each other.

We're not that close, just ladies who lunch.
