it means, if your godfather and godmother had a daughter, that would make you her godsister, well that's what Happen to me, because both my godfather and godmother are married and they had a daughter named lauren, n it's kinda cool
I think it means that a friend or family member asked one of ur parents to be a God parent to they're kid. Meaning if anything ever happened to the parents of you're God sister, your parents would take care of her.
It means that your parents are friends with another family that loves you so much that they would adopt you if anything ever happened to your parents. Some people use the words God parents casually and some people take it very serious. It basically means that your god sister’s parents are friends with your parents and they promised each other to be available in an emergency to help the family survive.
I have never heard of the term. it's sounds like a term your family made up for your godparents daughter. Like when your mom has a best friend , and maybe you refer to her as " aunt" . ? A special person who is not blood related
