sister friend

A person who is always there for you. Similar to a best friend but more, someone you hope will be in your life forever, she will be in your wedding and you two know eachother like sisters would.
Not developed with time, a person you meet and just know they are your sister friend.

I miss my sister friend, but physical distance can't keep us apart.

sister-friend

Your bestesting friend. Better than any friend. Who's been your friend for so long you might as well be sisters. You hate her you love her. She's your sister.

I have to make my sister-friend my maid of honor at my wedding or she'll kill me!

Sister-Friends

Sister-friends are girls that are so close, they could be sisters.. They can't live without each other. Side by side or miles apart, they will always be close. To each other, they are unforgettable. They act weird and smack butts without giving it a second thought. When they are happy, you are. When they feel pain.. you do. Living without them isn't an option. They are you're life. <3 You love them.

Bailey: I'm moving....
Sofia, Avery, Rachel, Lily, Teagan, and Claire: No you're not.
Bailey: yes, i am.

Everyone else: not if we have something to do with it.
*smacks booty* Bailey: whatever.
Mia: it doesnt matter. there is no way you're forgetting us.

Bailey: i don't think that's possible.. (laughs)

Everyone else: you'll always have us. and we'll be there for you.

Bailey: as you have always been! You're my sister-friends

your best friend's sister

a stupid comeback phrase that's used for virtually everything, even if it doesn't make any sense whatsoever

Friend #1: dude! i saw your mom last night! she was hot!
Friend #2: your best friend's sister!
Friend #!: you have a sister!?

dude: what happened last night!?
dude 2: your best friend's sister!
dude: shut up!
