your main best friend and someone who knows you better than anyone else. you know that you can trust them to keep a secret and this will be the person that wouldn't snitch on you if you did something illegal.

two or more best friends who are depressed at the same time. but its okay because at least they're depressed together

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.

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.
