The term used by British soldiers for confectionary sold out in the field. Usually from a pre-arranged fund for each Company of men, the Company Quarter Master will buy a shit-ton of Klakky and sell it cheap to the lads; Bottles of Cola, Pringles, Chocolate bars etc.
"Alright mate, you got any Klakky? I'm fuckin hanging out for a choccy bar."
