pinky

The hand gesture most closely associated with surf culture, shaka is formed by making a fist with the thumb and pinky fingers extended.

He had the pinky on his left hand bandaged due to a fall in his quarterfinal win over Taylor Fritz, after which he said he “tore a capsule” and that his finger was “crooked.”

He was all smiles as slipped the ring on his right pinky finger and held it up for the crowd to see.

He flashed his pinkies to reveal silver nail polish.

Some say the only requirement is an extended pinky and thumb.
