What is the name for a gathering of grandmas?

Bunch of old chooks

Do you really thing GN is anti-granddads?
Mollygo NO! Of course not! Why would you even thing that?
Although you must have paused to notice at one time or another that several Grandads have fled recently! I wonder why?

A wisdom of grannies.

I like that Franco.

In many ways I feel a lot stupider than my younger self so it would be rather nice to be credited with even a smidgeon of wisdom.

I don't think GN is anti-grandad. I think most people do view it as mainly for grand mothers and there are some areas where a grand-dad might fear to tread but, generally, a grandad can get involved as long as he has something sensible to say. I would not be interested in GN if it was just grandads or an area like 'grandads shed'.

Having said that, I think 'a wisdom of grannies' is definitely over the top!

there are some areas where a grand-dad might fear to tread
Cunco There are only two places where this Grandad fears to tread;
Cow pats and dog poo!
I think that makes a lot of sense! as well as a lot of mess!

Aunty Granddad's name works fine until you say it aloud
Mollygo I think I see your problem!
You're a Northerner where the short flat "a" prevails, whereas I lived for several years in the Home Counties where "Aunty" used to be pronounced "Arnty"; not "anti"

How about Granologists?

Let's face it, these terms are all stereotypes. At times on GN, I think I have met a pride, a prowl and a hug of grans, as well as a grumble of granddads.

as well as a grumble of granddads
Slow down a bit, Cunco!
Unless you're a Grandad too, I'm the only one around here and I certainly don't grumble
You might hear me howling at the moon occasionally, but that's only when I'm feeling lonely!
OoRoo.

When I meet up with several Grand Mothers it is usually a Gransnet Meet Up

A 'gloat of grandmas'...

A crown of grandmothers.
