A girl best friend is a young woman who will take care of you as if you were her own brother or sister.
She’ll hype you up and boost your ego when you need it, but she won’t be afraid to give it to you straight when you’re wrong.
She’ll never fail to be there when you need somebody to listen to your problems, anxieties, or insecurities.
She’ll sometimes know you better than you know yourself.
She will love you and have your back ‘till the very end.
Lastly, she will paint your world with her kindness. What more could you ask for?

Now stop reading this definition and go tell your girl best friend that you love and appreciate her. :)
Friend: “Dude... Did Maddie write you an entire song?”
You: “Yep.”
Friend: “And you two aren’t dating?”
You: “Nope. She’s my girl best friend.”
