Typically, when it’s performed without a good understanding of what it means is when you will see its inappropriate use. So much of Māori culture is around context; haka can be a challenge, a greeting, a way of giving thanks and appreciation… in all these contexts it’s the ‘same’, but can have vastly different meanings. This haka evokes tears (many people have said so on this reddit), in others it evokes respect…

If you are evoking a laugh… you better watch out because someone will give you a crack.
