The term 'Chittay' (also called 'Chitty') is a vernacular expression which seems to be widespread in the Channel Islands, particularly Jersey, but also other parts of the South West of England to refer to a pub quiz machine.
The origin is somewhat obscure, but one thought is that is originates from the word 'Cheat', which is a bonus that some quiz machine gives when the machine is just about to pay out.
(ii) Money/Loose Change
By extension, money that is either put into the quiz machine is sometimes referred to as 'Chittay'
The chittay at the King's Head was really paying out last night.
