Old Sayings
My Uncle Bun (short for Bernard) used to offer us a "cuckcuck" when we visited him and granny. It could have been a toffee, some dolly mixtures, liquorice lumps or ropes, gob stoppers - all sizes & colours, fish shaped sucks, jelly babies (we were assured they were all little boys for some reason) or sherbert dabs etc.
He was a very generous person and always had a stock of SWEETS - which, of course, he called "Cuckcucks".
PreWar days of long ago memories.
Anybody sell gobstoppers these days?
