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.

Slap Your Younger Sibling Day

On October 4th, anybody who has a younger sibling can slap them, and they cannot fight back, cry, or complain. They must accept the slap.

Older brother: Hey, guess what?
Younger brother: What?
Older brother: It's Slap Your Younger Sibling Day!
Younger brother: Fine, you can slap me.

Half Sibling

A sibling who you do not have the same parents as. HALF siblings either have the same mother only, or the same father only.

Since Wendy and Sally are sisters, and they do not have same father, they are Half Siblings.

Sibling Zone

Pretty much the Brother Zone and Sister Zone mashed into one convienient term.

Jen told me she liked me like a brother. How the fuck do you get out of the Sibling Zone?
