King Baby?

I have heard the phrase King Baby. Is this in our literature anywhere?

King Baby was a term originated by Sigmund Freud. It was intended to refer to a mental condition where the person thinks the world revolves around them.

It has been described as:
The childish ego traits seen in people who have reached adulthood without acquiring emotional maturity - a self-centeredness common to alcoholics and addicts.

The phrase appears in Pass It On and some other AA literature. Page references will be added as time allows.
