A branch of American Top Team in New Zealand released an interesting video recently.
It shows approximately 40 men doing a traditional Haka war dance, in their gi's.
The dance (or war cry) is traditional for the Māori people and consists of a choreographed dance with chants and stomping.
The dance originated as something that was done in battle to intimidate the enemy but it is used more commonly today as a sign of respect. It's often seen at funerals and special occasions.
The Haka has become more commonly known as Rugby teams perform it before international matches.
Perhaps we'll start seeing these before jiu jitsu matches.
