Someone with immense ego, and inflated self regard, who can often be found compensating for their small genitalia by driving a BMW or a Mercedes.
There's Larry again, trying to tell everyone what to do and swanning around like he's the Grand Poo-Bah of the whole place

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.
