Grandpatronize

Talking down to someone as if they are your Grandpa.

Don’t grandpatronize me just because I have an AOL account.
That kid just totally grandpatronized my husband.
Don’t grandpatronise me because I don’t know how to fix my auto correct.

grandmahood 

Same as motherhood, but for grandmothers. The longer version is 'grandmotherhood', but no one has the time to say it. The male equivalent for this term is 'grandpahood' and again, the longer version would be "grandfatherhood".

"Do you see Mary? Look how happy she is while holding her newborn granddaughter!"
"Ah, yes! She's definitely enjoying her grandmahood!"
