macomere
A special bond between a parent and the godmother of their kid. It's like they're best friends, but they also talk about your business like you're not there.
My mom and my aunt have a macomere relationship. They know my secrets before I do.
My dad and his friend’s wife are macomeres. They gossip about me in the grocery store.
My sister's godmother is a macomere. She texts me every day about her life and my sister's drama.
