Capoeira is an afro-brazilian tradition that combines martial arts, music and samba dance. It's really cool to watch because it's a different culture. It was brought to Brazil from African slaves years years years ago and it's still the main thing there.
I like to meet new places and cultures and this deff one i won't exclude before dying. There are some techniques used such as elbow strikes, slaps, punches, and body throws. In Portuguese capoeira literally means "chicken coop" so it is likely that the name originated as a derisive term used by slave owners to refer to the displays as chicken fights.
I leave you with a cool video i found in Youtube. Check it out.
