Instagrandma 

Someone who doesn't know how to properly use Instagram.

A grandma who collects and overshares her grandkids’ photos, but doesn’t actively engage in raising them

Maeve: like usual, Maryann has shown me ton of pictures of her grandkids, but when I asked her when was the last time she spent some time with them, she couldn’t give me an answer..
Linda: she’s such an Instagrandma, isn’t she

Instagrammar 

Instagrammar: Shorter than Facebook jabber, not as terse as twitter-speak, and full of tags; Instagrammar is the unique form of language found on the photo sharing application Instagram.

"From the photo I think she was having lunch in The Mission but I couldn’t make out her Instagrammar".
