The process of befriending the best friend(s) of your best friend. Given the mutual common best friend, a relationship can easily be formed with your best friend's said best friend(s).

My best friend's friends came to visit this weekend. I instantly became best friends with them through the process of Osmosis Besties. We are now one group of real life Besties.

Exclusive besties

Best friends that are a step more than besties but not quite romantic partners.

Kristen and Frank were exclusive besties because they would always been seen together and if they were ever apart people would ask where is your other half. They would share their deepest, darkest secrets with each other.
