estrofest 

A situation devoid of male influence. Boxes of Kleenex, Oprah and tear-filled confessions intermingle with hugs and handicrafts purchased at Pottery Barn. "Dishing" seems to be the most popular activity at an estrofest. Balanced budgets and letting the mind overpower the heart are conspicuously absent from such gatherings. Typical estrofest buzzwords tend to include "cycle", "biological clock" and "spotting". The opposite of a sausagefest.

My wife had her friends over last night. What a freakin' estrofest! They drank mimosas and dished about their significant others. There was so much rampant emotion in the room. Now where's the Kleenex? I could have sworn we bought a six pack of boxes last Tuesday!

estrofest 

A yearly festival in western Michigan involving only women (and the occasional gay man), with a yearly theme. (Ex. 80's prom, rave, etc.)

Lots of booze and ladylike love going on!
Decorations include banners made of bras and panties.

Men are allowed only under the pretense that they are slaves of some sort, cooking, cleaning or beer wenching.

Dude I can't wait for estrofest this year, last year's prom was awesome!

Estrofest 

A group of women getting together to watch chick flicks, drink wine, and inevitably cry on each others shoulders.

I left for the weekend while my wife and her friends had an estrofest.

Estrofesting 

A group of women, getting their shop on.

Walking into Fashion Bug during the bogo sale is a sure way to drown in estrofesting women.
