Trending: Team New Zealand's Haka Dance

Team New Zealand performed a Haka dance before the game.

Check this dance video out.

On Tuesday afternoon team USA basketball and Team New Zealand tipped off during the FIBA World Cup Tournament in Spain.

But before the game started Team New Zealand performed this Haka dance. It's a traditional war dance challenge for the country.

But the best part may have been the looks on the faces of the Americans. They seemed very unfamiliar with the tradition, which gave way to some very confused looks.
