Sister-in-law

The woman who doesn’t come to your wedding because she has more important things to do, yet expects you to pay for half of her wedding and will upend the entire family unless she gets her way. She is usually supported by your mother-in-law who somehow always takes her side in every possible argument.

Your sister-in-law thinks she’s entitled to you paying for half her wedding yet she has the audacity to not even come to your wedding.

Similar to "soul sisters", stake sisters share a deep, unexplainable connection, often about strange, obscure eccentric, or dark subjects, leading them to think their ancestors may have been victims of the witch hunts in Early Modern Europe and Colonial America. Connection to any formal or informal version of witchcraft is not required, simply the type of person whose interests may lie in the spirituality of the natural world or have taken them on a different course than the mainstream.
