Grand Poo Bah 

A Grand Poo Bah is any overbearing and pompous authority, often claiming numerous titles, roles or distinctions and frequently overplaying their hand. An overstuffed shirt. Someone who expects others to lick up to them for nothing. From a character in the 1885 Gilbert and Sullivan operetta The Mikado. Not to be confused with the Grand Pooh Bear, who is someone else again.

There's Larry again, trying to tell everyone what to do and swanning around like he's the Grand Poo Bah.

Is a title given to someone who holds an exalted position.
The name has come to be used as a mocking title for someone important or high-ranking and who exhibits an inflated self-regard.

"Fred Flintstone and his friend Barney Rubble were members of the Loyal Order of Water Buffaloes Lodge No. 26. A high ranking elected position within this organization is Grand Poobah or Grand Imperial Poobah. Poobah is a title of respect and often is linked to might in a role."
