God sibling in law

When your god sibling gets married their spouse then becomes your God sibling in law.
Usually when your sibling gets married their spouse becomes your brother/sister in law, in this case we want all to be welcomed to the family by including our god siblings spouse. Therefore you can refer to them as your God sibling,or God brother/sister in law.

Today, I went to the mall with my god sister in law.

Me and my god brother in law went to see a movie.

My god sibling in law took care of my pet while I was on vacation.

New sibling syndrome

When children who have recently acquired a younger sibling feel so excluded that they pretend the new member of the family simply doesn't exist.

Mary: "Who is that?" (motions to John's younger sibling)
John: "What are you talking about? I don't see anything."
Mary: "Oh John, I forgot you are still suffering from new sibling syndrome."

Younger Sibling Privilege

A phenomenon in which parents allow their younger children to participate in certain activities that they did not allow their older children to participate in when they were that age.

This is an example of Younger Sibling Privilege: When Johnny turned 16, his parents told him he could not work toward earning a drivers license. When his younger brother, Timmy turned 16, his parents registered him for driving school.
