Instagramma

An old lady who uses instagram like she's one of the hip kids of today. These kinds of grandmothers do one of three things: post multiple pictures of the cookies she's baked, stalk her grandkids by liking all their posts, or post pictures of herself taking selfies.

My grandma started using Instagram about a week ago...she's been posting so many pictures of herself, we've been calling her an instagramma
