Shaka sign

The shaka sign, sometimes known as "hang loose" is a gesture with friendly intent often associated with Hawaii and surf culture. It consists of extending the thumb and smallest finger while holding the three middle fingers curled, and gesturing in salutation while presenting the front or back of the hand; the wrist may be rotated back and forth for emphasis. The shaka sign is similar to the letter Y in the American manual alphabet in American Sign Language or the sign for number six in the Chinese hand counting symbol. The shaka sign should not be confused with the sign of the horns, where the index and pinky finger are extended and the thumb holds down the middle two fingers.
