Sister

Can either be a demon from hell, or your friend. Usually tries ruining your life and stealing all your parents love. Usually toxic.

“My sister just took me to the movies”
“not again, my sister stole my fucking car.”

Younger sister

The baby your mom gave birth to who isn't you. The one who is sometimes a curse, and sometimes a blessing.

Person 1: My younger sister photobombed me and now it's a meme, and a sticker!

Person 2: It's a gif, too!

Person 1: Oh boy, there goes the rest of the schoolyear.

Person 1: Who spread this rumor about me!?!?!?

Younger sister: Kat!

Person 1: Thank you! I'll tell her to take it down.

slug sisters

Two women who have had sex with the same man and remain or become friends.

Julia and I knew that someday we would become slug sisters. We just didn't know that it would be with Mikey, although neither of us were surprised.

Sister/brother/cousins

When sisters share a baby daddy their offspring would be sister/brother/cousins.

Or if a brothers have the same baby mama their offspring would also be sister/brother/cousins.

We not just cousins, we sister/brother/cousins.
