Hawaiian hand gesture. It has many meanings. Originally it means to "hang loose", or to chill and be laid back. It can be used as a positive reinforcement. If somebody did something good, cool, or righteous; You can give them a shaka as a sign of approval or praise. It can also be used as a welcome/goodbye sign. Most people would give the shaka as a sign of wassup or hello, use it as a way of saying goodbye, and even use it as a thank you.

To make a shaka:
1. make a fist (not a tight fist)
2. extend both your pinky and your thumb.
3. lightly shake your hand (too fast makes you like retarded or like a tourist, and too slow make you look stupid.)
4. If you don't want to do the shake, you are also able to do the "I'm tuff" motion. In a downward motion, move your hand. Giving a kind of downward wrist flick at the end. It gives you a more "i'm bad look". It's mainly used by old school Local boyz.

Shaka (sometimes spelled Tshaka, Tchaka or Chaka; ca. 1787 – ca. 22 September 1828) is widely credited with transforming the Zulu tribe from a small clan into the beginnings of a nation that held sway over that portion of Southern Africa between the Phongolo and Mzimkhulu rivers. His military prowess and destructiveness have been widely credited. One Encyclopaedia Britannica article (Macropaedia Article "Shaka" 1974 ed) asserts that he was something of a military genius for his reforms and innovations. Other writers take a more limited view. Nevertheless, his statesmanship and vigour in assimilating some neighbours and ruling by proxy through others marks him as one of the greatest Zulu chieftains.
Saying "Shaka ? Shaka THIS ash*le" followed immediately but throwing a spear through directly through the eye socket of some wanna be gangster trying to be all Hawaiian like shaking that stupid shaka hand gesture at you - then exclaiming "stupid motherf*cker!"
