1.
When you are forced to be phony friends with someone you hate due to sharing the same work environment.
Mary: "Wow, did I just see you talking and laughing with Jane?"
Sarah: "Ya, she was transferred to our project - so now we're on the same team and are BFF's"
Mary: "Really? I thought you hated her?"
Sarah: "Oh I hate her fucking face. We're Best Fake Friends now."
