re: Most unique grandparent names (what their grandkids call them) you've heard of?

Paw and big momma

My grandmother and her sister didn’t want cute names or traditional names. We always called them Susie & Madge. Now my dad has followed in their footsteps, and he’s just Randy. My Mom is Nana

Big Poo and Honey Moo. My next-door neighbors.

Mom-may
Pop-pay

Now? Pawpaw and mawmaw/ma’ammaw. The most recent generation of grandparents’ egos refusing to allow people to call them a name universally recognized for grandparents is comical.

My MIL wanted to be called Geaux-Ma.

Everyone immediately shot that down.

I called my grandfather “Grand Neg”. My dad was T-neg

The grandparents wanted to be called Grand-mere and Grand-pere. The oldest grandchildren pronounced that as Grossy and Grumpy, and that stuck.

My mother's name was Fran. We called her GranFran.

I had a childhood friend whose grandparents were called “Moose” and “Poose” - no idea why, but always thought that was hilarious. Another friend’s Hispanic grandmother lived with their family - they called her “Gon-Guh”. Whenever I visited there I could never call her that without laughing - it always reminded me of someone who should be swinging on a vine in a Tarzan movie My own grandparents names were pretty boring:, mom’s parents were just “grandma” and “grandpa”. But my other grandmother was called “Big Mama”… by her own choice . My mother could never bring herself to call her that however as she thought it was disrespectful to call her mother-in-law “big” (probably because that grandmother literally WAS big) so she always just called her “Mama (last name)” instead.
