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.

The sister of my girlfriend/boyfriend. For when you're not in a lawful/legal relationship with someone, but still have a close relationship with their relatives. Relative-In-law is a legal relationship. Relative-Out-law is a relationship with no legal standing.
