It's a traditional tribal war dance that runs deep in New Zealand's history and if you're lucky enough, you'll get to see it in person. Usually associated with the national rugby team, the All Blacks, it has now be reintroduced to the world through basketball. Before "going into battle" they perform this dance to intimidate their competitors. However, it looks like they just mesmerized team USA. Although, if you've never heard of it... I could see the mix of confusion and amazement!
