Aside from our immediate family, the most valuable relationships in young adults' lives is their relationship with their best friends, or any female friend in general. This "unspoken" girl code is the holy grail of do's and don'ts when it comes to female friendship. Girl code is the unwritten set of rules that exist between a girl and her best friends. Simply stated, girl code is the commandments that outline the DO’s and DON'TS of a good friendship. Scroll down for the most basic and important set of rules when it comes to making or breaking a friendship:

1. Don't ever go after your friend's ex. This rule is so well known, yet broken so often and is the reason most friendships unfortunately end. You're supposed to hate her ex, not date her ex.

2. If your friend tells you something in confidence, it is your job to not go blabbing it out to the entire world.

3. No matter how close you are with a girl, if you are out and see this girl is too intoxicated and can't control herself, and is alone, you make it your job to get her water and keep her safe. You would want someone to do the same if you were in this position.

4. If a girl needs a tampon and you have a tampon—help her out. We all know how that situation feels.

5. If your friend asks how her outfit/hair/makeup etc. looks, BE HONEST. If your friend goes to you wearing bright blue eyeshadow, I would save her the embarrassment of going out and mortifying herself by telling her to maybe tone it down a little.

6. If something your friend does bothers you, make it your obligation to respectfully talk about the problem with them, and don't talk about them, because they will find out somehow.

7. As gross as it is,: it is a friend’s duty to hold her friend's hair back while throwing up.

8. We are girls, full of hormones, and this does make us emotional people. Be prepared for drama when surrounded by girls, but don't end friendships because of a little argument.

9. If your bestie is depressed and in a funky mood, don't make her feel worse by not comforting her. Drive to her house with ice cream, and be her shoulder to cry on.

10. Girls group chats are a vault of secrets. Like they say, what happens in Vegas.... well what happens in a girls group chat, stays there.

11. Comfort your friend when she goes through a bad breakup/relationship. Definitely don't hook-up or become friends with the jerk who broke her heart.

12. ALWAYS be down for a drive-by if your friend needs it.. no matter what the situation or reason is.

13. Even if your best friend is wrong and messed up severely, they are your friend and you will stick by them. If you don't agree with it, tell them, but do not go against them.

14. Girls nights are a must in every friendship. You do not need to go out and party all the time.

15. Who needs a boy to go on cute lunch dates with when you got your girls?

16. Our inside jokes and secret code names for everything stays "inside."

17. If you have a boyfriend, you do NOT forget about your friends. Because who is going to be there when he breaks your heart?

18. If your best friend hates them.. you hate them

19. Keep the gossiping about the latest episode of Real House Wives, and stop gossiping about your friends.

20. Support your friend's opinions, values, and hobbies. Also support them on social media by always being their first Insta like.

21. Always tell a girl if she has smudged makeup, food in her teeth, toilet paper on her shoe, or any other mishap.

22. If you're in a fight with your boyfriend (or anyone), chances are your friends are on the other end of the phone receiving all the screenshots. It's your duty to help your fellow sister out with good responses to win the argument.

23. Like Christina Yang and Meredith Grey, always dance out your problems. It is just as therapeutic as any stress reliever is.

24. If your friend needs to go to the bathroom, you never let her go alone.

25. Do not break GIRL CODE.

All friend circles have different guidelines and boundaries you can and cannot cross. Make sure you respect that. You need your friends just as much as they need you. Even when you can’t stand yourself, your girlfriends will. Remember that and show them some love every once in a while — you’ll never regret spreading a smile. Whether they are your best friends or you just met, girl codes are put in place to help girls support one another as women and maintain healthy friendships with those whom you really care about.
