"De-escalation Verbal Self Defense, also known as Verbal Judo or Verbal Aikido,[7] is defined as using one's words to prevent, de-escalate, or end an attempted assault.[8] It is a way of using words as weapons or as a shield. This kind of 'conflict management' is the use of voice, tone, and body language to calm a potentially violent situation before violence actually ensues.
