A bestie is a person that will always be next to you. She/he will have your back on everything. They have to accept you the way you are and if they don’t there not a real bestie.

The best thing that has ever happened to you. They will always have your back and they tell all their secrets to you. You have so many inside jokes that are hilarious. They are the best thing that has ever happened to you so don’t lose this person because you love them so much. xoxo

A friend that is more than a Best Friend! Who cares about you and talks to you at least 7 or more times a day! Another word for Bestie is Soul-sister or Soul-brother. You can have multiple bestai but it is called Bestai not "besties" because that doesn't go with the people!
Examples *EXAMPLE 1*
Madison: Your my Bestie and so is Mikki!
Matty: You are my Bestie so is Elizabeth!
Madison: We have Bestai!...XD
Another Example* EXAMPLE 2*
1 Matty and I are besties
2 Who is your bestie? I have bestai. Multiple besties; Mikki and Matty are my bestai. But Matty is my bestie, and Mikki is my bestie.

Anyone and everyone. A form of a kind warming greeting. Also commonly used to mock someone in an argument.

Can be anyone. From a stranger on the street, to your physics teacher, to your enemy or your boy toy. Maybe you love them, maybe you don't, maybe you want to hug them or punch them. Use it often and liberally. ANYONE can be your bestie. Don't be shy or afraid to force this label on your relationship with people. But don't forget to declare and define this relationship with your bestie early on. Let the world know who is TRULY your bestie. You can have more than one. It's an open, poly vibe. Stay thriving besties. Mwah.
