Mongo 

Cross between a monk and a Ego= MonGo.

A monk devotes himself exclusively to a religious life, and ego itself is self personality.

For me a Man with a ego is a 'Mongo' , descriptions a man who makes his life, religiously making it all about his
very own Ego.
My justice to a very bad man. Ladies and Gentlemen I give you My 'MonGo'

another name, you do not have to say , he is a man with a huge ego, instead you just give them a name (he is a MonGo)
