*Not to be confused with "one of the guys" or "girlfriend"

The girl who befriends the wierd kid with pink hair, ACDC shirts, and floppy skate shoes in middle school. The girl who is completely unaware that this awkward, scrawny kid will eventually become the guy of her dreams. The girl that thinks she's just being nice but all the sudden realizes she's not just nice, but lucky. As time goes on she realizes she has become his "bro" and, in his eyes, is no longer a specimin in his dating pool. She has to act as though she's interested in hearing him ramble on about the hott girl he met in physics or the 'totally sick' new deathcore band he just downloaded on to his iPhone1700. The girl who has to sit there and watch him snuggle up with another chick who looks just like her and pretend she has no idea that she's the third wheel. She's the girl who when she says she's 'confused' on where their relationship stands and he pulls something out of his ass like:

"Oh, I know how the lines can get blurred sometimes. It's cool dude."

- (as if you had just apologized)

Being the "best girl friend" is almost like being the average looking sidekick to the sexy super hero. Sure, it's awesome to be seen with him...but who ever notices her? She's the girl who wants what she can't have and the boy...is all too oblivious.
You're my best girl friend, dude. Our relationship is awesome. Why would you want to screw that up?

A girl best friend will there for you no matter what. Even if you do something horrible they will be by your side. It’s someone you can trust, and be able to tell them everything and anything. Someone you want to tell something first before your girl friends or mom you want to tell them first to see how proud they are of you. A girl best friend isn’t just anyone it’s the person that tops everyone off, the girl that you want to watch series with and stay on call with all night the person you say goodnight and good morning to, the one who knows you better then anyone and knows your favorite food and favorite show she’s almost like your sister and you treat her like a princess. A girl best friend will give you advice about girls and tell you how to flirt and everything and she would love you no matter what
So what’s up with you and savannah? Oh she’s my girl best friend

(noun) a girl best friend is the one special woman in your life you love, platonically.

She loves you like a brother, and doesn’t judge you for who you are.

She may have a small crush on you one time or another. You may have a small crush on her one time or another. This is completely normal.

Hug her, complement her, protect her, make her feel special, even if she isn’t your girlfriend.
She loves you, show her some love too.

She IS your best friend after all.
My girl best friend is the one person that will show me empathy when my guy friends won’t.
