It's a nasty old-style of full-contact karate. Maybe you saw the famous 1920's video of the founder killing a full-sized bull by choping off his horns and then burying his fist in the bull's neck? I believe the video is available on the internet.
NARF! I'm glad you're apparently devoted to non-full-contact forum bashing. Me, I stick to trying to fight the cholesterol monster in tae-bo fitness classes, pretending to be Jackie Chan. From the "Action GOOD, Violence BAD" school of martial arts, with a hip-hop/disco beat.
