The word is haka.
The idea came up about 10-15 years ago, I think as an advertisement in an English magazine.
The title was "All Blacks psyched out by English Haka".
The picture showed a morris side (6 dancers) in white, with hankies up in the air, left legs up and looking as if they're about to dash across to the other side. It might have been Saturday Night On from the way they're moving.
The words at the bottom say "Definitely a Dry Blackthorn Day."
I made an A3 photocopy and stuck it on card for display but its too big to scan.
Maybe someone can find the original.
