I would possibly claim it as a new word. But it seems to be a high value fashion den in the UK - Liberatti. Instead I will borrow the word and create a new definition for it.
What is a Liberatti? It is someone who was born with a trust fund silver spoon in their mouth it seems. They get up and bemoan how horrible people have it and the government must do something with all of our money while hiding their own assets. They roar loudly and wave their arms frantically whilst in high dungeon over their pet causes. But if they are forced to really put some of their own personal skin in the game, they turn tail and try to claim everyone who was outraged did not understand their intelligence. In other words a Liberatti is a phony.
