An extremely close friend who although isn’t related to you biologically is like a dream sister you would see in like a movie. You can tell her anything she’s prbly one of the closest people in your daily life. Always there for you, for when you laugh and for when you cry. always spending time with you no matter the shenanigans you pull. Someone who can lift your troubles by smiling. This type of person is someone that you end up knowing for a while and you should be extremely grateful for their presence in your life
I swear that’s my Big Sister , I wouldn’t be here without her by my side

A big sister will mostly likely treat u like trash but deep down inside they love you. Sometimes when a baby sibling gets hurt they will most likely care for them like mothers but as a sibling.
*baby brother gets yelled at for spitting at his brother* then big sister comes in. *big sister holds him and hugs him for comfort*

A crazy female teacher who is "always watching you".
Derrived from George Orwell's novel Nineteen Eighty-Four, where a character named "Big Brother" and his "Thought Police" are keeping track of everything and everyone.

Big sisters tend to be severe in punishment as well.
Big Sister:

Mme. Zylberstein.

Any crazy old female teacher you had who appears to have eyes in the back of her head.

Let's go to my house later, you don't want to meet my big sister.

I asked God for a sign that the devil was walking amongst us, and my big sister entered the room.

I'd say you're the most selfish person I know, but then I realized I have two big sisters.

My big sister said she was going as The Wicked Witch of the West for Halloween, so I assumed she didn't feel like dressing up this year.
