Everyone needs their own coded ways of mocking the Dara Happans.
Perhaps the Pelandans call a large, thick crust, completely untopped
and slightly undercooked pizza a 'Yelm Pizza' -- they tell the DHs that
it is because it is pure and deep (and it is undercooked to ensure it
is unblighted by dark 'eclypses'), so Yelmies visiting Pelanda feel
honour-bound to chomp their way through these under-cooked and undertasty
pizzas while everyone around them is enjoying some far more
enjoyable treat. Of course, the Pelandans know that this is a 'Yelm
Pizza' because, like Yelmies themselves, it is bland, stodgy and
missing out on all the good stuff.
Taking the pizza, as it were
All the best
