While the term "other half" isn't supposed to be literal, we all have someone in our lives that we would truly be lost without. So many good memories and important lessons come from the experiences we share with our best friend, often because the relationship has become so strong that you two are basically the same person. Here are 20 indications that prove your best friend is so much more than the title "best friend" can describe.

1. You have your own language.

It's necessary for discussing girl talk or decoding sentences between bites.

2. And when words fail, the look tells all.

You two are basically telepathic at this point.

3. You regularly go out in extremely similar clothing.

Your wardrobes are 100 percent communal, too.

4. And he/she is the only person you enjoy matching with.

It's especially exciting when you have an unplanned twinning moment.

5. You have at least one song that is yours and only yours.

The rest of the world can totally judge the chaos that ensues whenever it's played.

6. People are surprised if they see you guys apart.

Whenever you go out alone or with other friends, someone is bound to ask where your other half is.

7. "Friends" isn't even an appropriate term for your relationship.

The hospital got it wrong: You guys are clearly long-lost siblings who were separated at birth.

8. You're not afraid to give each other tough love.

Honesty is always appreciated between you two, since you know it's meant to be helpful rather than hurtful.

9. You have no secrets from each other.

He/she is always the first person you call to discuss any major life event (in the rare case that he/she wasn't there to witness it in the first place).

10. And you never get into arguments, because there's always something new you have to tell him/her.

Who else would really be able to understand your life struggles?

11. You're always camera ready when you're together.

Even when you're not on fleek, you two will never turn down a photo op.

12. Everything reminds you two of your inside jokes.

And it annoys everyone around you because they never know what you guys are talking about.

13. He/she is instantly by your side in any sort of crisis.

They will also provide the junk food and words of encouragement, if necessary.

14. Your family considers him/her as one of their own and vice versa.

Considering how much time you two spend at each other's houses, it was only a matter of time until your families faced the facts.

15. They could humiliate you off of the face of the earth, but they choose not to... usually.

This is the one drawback of constantly venting to him/her about everything.

16. You hate the same people.

There's a 95 percent chance you guys initially became friends over your passionate dislike for someone.

17. You're incapable of being "too weird" with each other.

At some point in your relationship, you guys crossed the point of no return.

18. You tag him/her in funny posts all the time because everything reminds you of each other.

You can easily attribute a majority of your Instagram, Facebook, and Snapchat notifications to your best-friend shenanigans.

19. When you're reunited after a while, it's as if nothing has changed.

You're so close that you don't even have to communicate regularly in order to pick everything back up from where you left off.

20. And that's because you know you two will be friends forever.

You're stuck with each other in the best way possible.
