A person forming a circle with their arms overhead to gesture 'OK' or 'all good,' the visual opposite of the crossed-arms 'no' emoji. It's used to confirm plans, agree with something, or signal approval, and like its counterpart, it derives from East Asian gestural convention (arms-overhead circle = OK, as opposed to a thumbs-up which isn't universally positive). Trivia: this pair (NO/OK gestures) was designed as a matched set from the start of emoji, making them one of the earliest examples of intentionally paired opposite-meaning emoji.
