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.

Get the depressie bestiemug. Friends who often drink so much every time that go out that they do not remember the night's activities. These friends consequently have a solid relationship built off of forgotten yet (hopefully) spectacular memories.
Kellie and Rebecca aren't just best friends, they are blackout besties, they rely on everyone else to remember their nights but this makes their friendship even stronger.
