Performing a Haka with the team is clearly the best way to intimidate your opponent pre-game. I don’t ever want to see these guys on the field…
Some background on the haka:
The All Blacks, the international rugby union team of New Zealand, famously perform a haka (Māori traditional dance) immediately prior to all international matches. The Haka is also performed by other New Zealand national teams, such as the Kiwis (rugby league) and the Tall Blacks (men’s basketball).
