Before there was Meredith Grey and Christina Yang, Miley Stewart and Lilly Truscott, and even Jimmy Fallon and Justin Timberlake, there was Monica Geller and Rachel Green. They were the definition of true friendship. The key to Monica's and Rachel's true and everlasting friendship is that they made each other laugh till their stomachs hurt, were there for each other through everything, and then get some dirt on each other when they were drunk so they could never leave each other. They would even argue and fight but their friendship would never settle. Here are some laughs and reasons why Monica and Rachel are the BFF goals!

1. When you hang out it's completely normal to just stuff your faces and eat whatever you want without the judgment.

Binge on!! You deserve it. Forget those haters!

2. Your personal bubble doesn't apply to each other. You need your nose scratched? I gotchu!

When it comes to BFFs, there are zeroboundaries.

3. She’ll always hit you with the truth

Always honest without question. Sometimes even without a filter!

4. You literally fight like sisters

Sometimes the claws come out and a cat-fight ensues

5. But then can't stay mad at each other because you got gossip to tell and she's the only one that will understand.

Hug it out....then spill the beans!!

6. Even if times get awkward she's got your back

She'll get you out of those tight situations for sure!

7. When it comes to game night, everybody better watch out, because both of your competitive sides come out to play.

Yupp, even when you roll the dice to see who goes first, that gets ugly too.

8. The thought of being apart is simply terrifying and depressing.

Can't even go to the bathroom without you.

9. When your BFF gets a new friend you're all like, "back off Felicia...she's mine!"

You belong with me. No one else!

10. You even plan your futures together

You've always been promising each other that when you’re both old and your husbands have died, you’ll move in with each other so you can drink daily, complain about your new young BF’s and keep each other company.

11. You are each other's go to person

Always and forever

12. You always go out together

Friends who party together stay together!

13. She's even there for you when you can't deal with life

Even when it's not your day, your friend has your back (and a few pints of ice cream and chic flicks).

14. They are your other half

You complete me!

15. And when it comes down to it, y'all aren't just best friends, but more like sisters

Love ya like a sister!!

Monica and Rachel were the OG BFF goals and they have proved it to us time and time again!!

So cheers to BFF goals!!

Go on and hug your BFF and tell them how much you love them!
