BYOJ Friend 

A BYOJ (Bail You Outta Jail) friend on the top of your friend hierarchy. This is the person who will answer your collect call from the county jail at 3am, and bond your ass out ASAP.

Jen and Kaley are, legit, the best friends ever. I mean, I have good friends but they are my BYOJ friends.
