Technically it's correct, but before finding out in this thread that in the UK they're "fish fingers", I was picturing guys so square they had corners in their 1950s' labcoats and suits... "It's fish. It comes in a stick form. We call it The Fish Stick."
Meanwhile, a name like "chicken nuggets" is catchier, draws one closer.
Nugget = bite-sized gold (well... two bites). Very clever marketing. Perfect marketing, in fact.
