It's a Brazilian form of martial arts. A guy does it in the park and I often see him when I run. Today there were three guys out kicking, jumping in the air, turning around. It's like martial arts dancing. Very cool. The guy I usually see also has weapons that he uses in his routines. I struck up a bit of a conversation with them about it today because it's really cool to watch.
