Gouging is when people get into a fight and one person tries to hurt the other person's eyes. This can be really dangerous because it can permanently damage someone's vision. People who gouge might try to use their fingers or even objects like sticks or knives to hurt someone's eyes. It's something that is not allowed in most combat sports or self-defense classes because it can be so dangerous. In fact, it's considered a foul in most fighting styles because it's not fair or safe. It's important to remember to always fight fairly and try to avoid hurting people's eyes or other sensitive parts of the body.
