Verbal Self-Defense (Tongue-Fu) is the art of verbal communication for personal protection. It is amazing how effective just communicating with the potential attacker could dramatically change the situation's outcome. It can take a conflict resulting in bodily harm and/or death to simply walking away unharmed.
Choose Your Words Wisely
Tongue-Fu is often not considered as an option, because the ego tends to get in the way. The ego is responsible for the majority of all conflicts between people and if just one of the involved ego's backs down, then the conflict usually won't occur. In order to have a fire you need fuel, oxygen, and a heat source. Take away any of these elements and you have no fire. The same applies to confrontation. Take away any of these elements, fuel (person), oxygen (words), or heat source (ego), and you have no fire (conflict). It's that simple.
