(Not spelt 'shaka bra')
Originating from Hawaii, Shaka Brah is used in the form of a Gesture rather than Speech.
It gestures symbolically, a positive atmosphere/vibe; which is why it is commonly 'thrown out' in those type of surroundings (e.g. the beach).
With your hand: Have both your pinkie and thumb up; middle three fingers down.
People say you have to make your fingers point a certain a way but no, it doesn't matter as long as you mean what it symbolizes.
:How to use the Shaka Brah Gesture:

You might hear people say you have to make your fingers point a certain a way but naw, it doesn't matter as long as you mean what it symbolizes. (;
