Haloti Ngata — Tongan War Dancer [Video]

Baltimore Ravens star Haloti Ngata frightened the hell out of a room full of people last night when he busted out an authentic Tongan fighter dance on stage … and TMZ Sports has the footage.

It’s called the Kailao … a habitual dance from Tonga (where his parents are from) … and the 340-pounder showed off his moves at the 3rd Annual Haloti Ngata Family Foundation Luau. 

The event raised more than $ 50k for local educational groups and teachers … and a whole bunch of Haloti’s teammates were there to support him — including Steve Smith Sr., Torrey Smith, Chris Canty, Justin Tucker and Courtney Upshaw. 

But Haloti didn’t just dance — he also SANG — busting out a rendition of “Rude” by Magic!  Check out the clip …
