The shaka sign is a common greeting gesture. It is often associated with Hawai’i. It consists of extending the thumb and smallest finger while keeping the three middle fingers curled, and raising the hand as in salutation with the back of the hand facing the person that is being greeted; sometimes the hand is rotated back and forth to emphasize the sign.
Hawaiian locals use the shaka to convey what locals in Hawai’i call the “Aloha Spirit,” a gesture of friendship and understanding between the various ethnic cultures that reside within Hawai’i, and thus it does not have a direct semantic to literal translation. Depending on context it can also be used to communicate notions such as “all right,” “cool,” “smooth,” and the like.
