I find the title misleading: there was no attack so no need to defend yourself and therefore no self defense.
But a smart way to sneak out of a dangerous situation. Well done.
I respectfully disagree. Self defense starts with situational awareness and includes things like preclusion and de-escallation.
Fighting techniques without something like Coopers Color Codes and IMOP are incomplete self defense approaches in my opinion.
