haka , n :
A group dance of New Zealand’s Maori people featuring rhythmic chanting, vigorous facial and arm movements, and foot stamping. Traditionally a war dance, today it is also performed to welcome guests, as a mark of respect at occasions such as commemorations and funerals, as a challenge to opposing teams at sports events, and for artistic purposes. Today is Waitangi Day, the national day of New Zealand.
