SUPERFISHPIE?

SUPERFISHPIE, a common cry, a howl, a shout, an exclamation! Of what, exactly?
Discussion over the matter pervades all of SUPERFISHPIE's citizens, from the anti-intellectual adventurers of the Very Dangerous Path to whoever happens to make a fish pie to the upper echelons of philosophers who preside in the nearest university/coffee shop.
Discussion is an engaging and interesting topic whatever the situation, but a visitor may have the feeling that SUPERFISHPIE's citizens all know what it means already and the whole matter is just an inside joke.
Such a notion, of course, is quite silly. SUPERFISHPIE truly means something or other to everyone. Probably.
