Facebook Phoenix
When someone decides to dump their old Facebook like it's a bad relationship and start fresh with a new one. They delete all their old photos. They forget their old friends. They're now a brand new person with a brand new life.
I deleted my old Facebook because it was full of bad memories and my ex's face.
I started a new Facebook and called it 'me, but better.'
I unfriended my old coworkers and called it 'the great unfriending.'
