Your grandma's grandmother. It's a family member in your family tree that you'll see at a family reunion, and will have no idea who they are. Then they'll go up to you and tell about how they used to change your diapers, and ask if you remember them from when you were a microcell. They get offended when you say no. ✌🏼
