1- Sibling's wife.
2- Spouse's sister.
My sister-in-law is a good person.
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.
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.
My sister in law married my brother. She is a whore, I bet she doesn’t know who their kids fathers are because let’s face it, she’s a nasty loosy whore hoodrat tramp.
The sacred sister law states that “If you find news or information that makes you feel uncomfortable, you must share it to your sister”.
The sacred sister law: Brit and char are sisters. Brit found a video about an onion that made her feel uncomfortable. Brit shared the video to Char.
