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.
