1. Sister from another mister
“Sister from another mister” is a fun and creative way to refer to a close female friend. It’s a humorous phrase that captures the essence of a sisterly bond without taking things too seriously. The phrase is a play on words that utilizes rhyme and alliteration, making it memorable and enjoyable to say.
The term “sister from another mister” basically says that you are sisters but not from the same parents, which might not make a lot of sense biologically but is perfect to describe the best friend who you treat like family.

This term is often used to refer to your best friend who understands and supports you on a profound level, and who is always there for you through life’s ups and downs. The phrase “soul sister” is an endearing way to express your love and appreciation for a close friend.
You would call someone your “soul sister” if you feel a unique and special bond with her that is more than just friendship. A “soul sister” is someone who understands you in a way that no one else can. This term is perfect for women who share a strong connection and feel like family despite not being related by blood.
3. Bestie or BFF
Calling someone your “bestie” or “BFF” is a playful and casual way to refer to a close friend who is always there for you. “Bestie” is short for “best friend,” and “BFF” stands for “best friends forever.” Both phrases are widely used both online and offline and have become popular terms of endearment for close friends.
Referring to someone as your “bestie” or “BFF” means you have a strong bond and connection with that person.

4. Sister by heart
When you call someone your “sister by heart,” it means that this person has a special place in your heart as if she was your real sister. It is a way to describe a close friend who you feel is a part of your family, someone you trust and love unconditionally.
Think about it this way – when you were little, you might have played house with your friends and pretended to be sisters. You might have shared secrets, giggled together, and even fought occasionally. Over time, you grew up, but that bond you formed with your best friend stayed strong. That’s what having a “sister by heart” is like – it’s like having a lifelong best friend who you can always count on.
5. Confidante
“Confidante” is a fancier term used to describe someone who you trust and confide in with your deepest thoughts, secrets, and emotions. A confidante is a person who you can rely on to keep your secrets safe and offer you support and guidance when you need it the most.
When you have a friend who is like a sister, it’s not uncommon to call her your confidante. After all, when you have a close friend who knows you better than anyone else, you naturally turn to her when you need to vent, share your feelings, or seek advice. A sister-like friend can be the perfect confidante – someone who you can trust with anything and who always has your back.
Think about it this way: a confidante is like a vault where you can store all your deepest secrets and emotions. And having your bestie as your confidante is like having a personal vault that also has a comfy couch, a box of tissues, and a never-ending supply of snacks. You can share your joys, your sorrows, your fears, and your dreams with your confidante, and she will always be there to listen, support, and advise you.
6. Surrogate sister
A surrogate sister is someone who is not related to you by blood but who feels like a sister in every other way. Maybe people often think you are sisters, and it just feels right!
It’s like having a sister who you chose for yourself, someone who you share a deep connection with and who you consider to be a part of your family. Calling her your surrogate sister is a warmhearted way to express how much she means to you and how important her friendship is in your life.
Your surrogate sister is someone who you can count on to be there for you through thick and thin, someone who you can share your joys, sorrows, and adventures with, and someone with whom you always have each other’s back.
7. Kindred soul or Kindred spirit
When you meet someone who shares a similar outlook on life, has similar interests, and just “gets” you, they might be your kindred soul or kindred spirit. It’s like finding a long-lost friend that you didn’t even know you were looking for!
A kindred soul is someone who you feel an instant connection with, almost as if you’ve known each other for lifetimes. She understands your quirks and your passions, and you feel comfortable opening up to her about anything. A kindred spirit is someone who you can talk to for hours on end, and it feels like time just flies by. It’s like you are speaking the same language, even if you are from different parts of the world!
It’s a beautiful thing to find someone who shares your heart and your spirit, and having a kindred soul in your life can make all the difference in the world. Calling a friend who is like a sister your kindred spirit is a wonderful reminder of how special it is to find someone who just “gets” you.

8. Honorary sister
An honorary sister is like a sister-in-law but without the troubles of marriage. She’s a friend who has earned a special place in your heart, someone who has gone above and beyond to support you, love you, and make you laugh. Think of her as a sister from another mister who has earned her stripes through years of loyalty and companionship. She may not share your DNA, but she shares your heart!
An honorary sister is a title that is not given lightly. It’s reserved for a friend who you can always count on, even in the most difficult life situations. She’s the one who brings you soup when you’re sick, listens to you rant about your boss, and celebrates your triumphs as if they were her own. She’s the one who knows all of your secrets and loves you anyway. So if you have an honorary sister in your life, cherish her. She’s a rare and special treasure, someone who has earned a place in your family for life.
9. Soulmate
While the term “soulmate” is used more often to refer to a romantic partner, you can absolutely have a platonic soulmate, especially if this person is your best friend who you call your sister!
For example, if you’ve been through a lot of together, and your connection feels almost unexplainable, you might consider your best friend a soulmate. If you have a deep understanding and appreciation for each other that goes beyond words, and you feel like you were meant to cross paths, don’t hesitate to describe your bestie as a soulmate.
Generally, if you feel like your best friend is your perfect match in terms of personality, interests, and life goals, you might consider her your soulmate in a non-romantic sense.
10. Virtual sister
While the term virtual sister, when you first hear it, might be confused with online friendship, it’s actually another way of referring to your close friend. It comes from saying “she is virtually my sister”, meaning she is like a sister to you, but you don’t have a blood relation.
The bond with a virtual sister may have developed through mutual interests, similar life experiences, or shared values. She’s someone who you may not have known for your entire life, but who feels like she has been there all along.
Having a friend who is virtually a sister can be a wonderful thing, as she can provide a sense of belonging and sisterhood even if you don’t have a biological sister or live far away from your family.
