Beyond just the sport of boxing, it's also used in debates or discussions to strongly assert one's argument. It humorously conveys a challenging feeling, like "Let's go a round!"

This emoji also symbolizes the fighting spirit to overcome adversity. It can express the passion to face the impossible, like in the movie 'Rocky,' or be used to celebrate a complete success, like a 'KO victory.' In Korea, it's linked to the "fighting!" culture and is also used for encouragement.
