big sister 

Government surveillance efforts that utilize surrepitious methods and deny any involvement because they lack the testicular fortitude to defend their own actions.

"Red light cameras are classic Big Brother, but NSA scanning of Google Earth footage is totally Big Sister."

Best Sister 

It is a relationship between two sister, it is more than a best friend and means more than the word sister. If you have a sister that you are best friends with she is your Best Sister!

My sister Jenna is my Best Sister.

soul sister 

boy or girl; someone of the opposite sex who you have everything in common with from music taste to birth defects. Even if you don't speak to this person frequently, when you do you can become like siblings within the hour.

Girl #1: "We have the same favorite song! Our parents have the same name! We both are allergic to Heinz Ketchup!"
Girl #2 "Why don't you marry him then?"

Girl #1: "I would, but we're already soul sisters!"

kiss your sister 

Nothing exciting; not good or bad. Often an expression used when something good offsets something bad, and you come out even, i.e. in card games where the points for a hand may split evenly.

How was your day?

Eh, you know, kiss your sister. A little up, a little down.

Little Sister

A younger female sibling that can be annoying as hell and you probably fight a lot with. But no matter what's going on, she will always be by your side wether in good or hard times and help as much as she can to make you feel better when you are down.

Although my little sister makes me going crazy literally all the time, she's the best one of them all
