A saying fellow road men and chavs use to greet one another. Once “ah bah” has been heard many other members of the tribe will then repeat the saying - this asserts love and peace into the otherwise quite hostile group.
A gracious saying created and founded by roadmen king pins, the klinic massif.
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.
