Ahh. This one should be simple for you. As you are the originator of the frostbite fighting style.
Basically, you're focusing your hyouton chakra, and not actual ice into the air around the target. By doing so, it'll lower the temperature of the air and cause the opponent to get a major brain freeze by freezing the areas they breathe in. An ideal situation is when you see the opponent inhaling for a katon/fuuton justu. If there are no further questions, you may begin molding the chakra around my head.
