Bestie 

A friend that can be trusted in all circumstances without holding back to any detail yet reliable to default

Margaret, Kay and Douglas are friends looking out for each other back. Therefore the three calls each other bestie or besties because their friendship knows no boundaries

Bestie, initially short for best friend, but often used between virtual strangers on the internet. It can also be used between people in the LGBTQ+ community who feel a kinship, share a mutual interest, or are agreeing on something.

Person 1: Suits were invented to be worn by Katie McGrath.

Person 2: So true, bestie.

Bestie 

You're "best friend" for the moment. Could change hourly and can have more than one. Typically a wingman (or wingchic) in a bar

Guy in bar: Hey can I buy you a drink?
You: Of course! But only if you buy my bestie one too ;)"
