sister-in-law 

Your up there but you know you really shouldn't be.

In golfing terms shanked a shot, lands on green next to pin.

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.

Sister-in-law 

The person who will ruin your wedding.

My sister-in-law ruined my wedding by demanding I pay for her wedding and starting a family fight. Of course my mother-in-law took her side.

Sister-in-law 

The ultra important, high falutin, and just all around annoying sister of your spouse. She will not be at your wedding because she has more important things to do, and if by chance she shows up, she'll ruin it. She's your mother-in-law's teammate and soldier.

The ideal sister-in-law is one that resides six feet below the ground in a cemetery, right next to the ideal mother-in-law.
