Using this tonight!
had a visiting white belt try the original arm bar defense on me. he told me when i was trying to break his grips he saw the defense online and he couldn't be arm barred. i didn't have the hear to say anything so i just tugged and he tapped.
I remember having someone in an armbar and they did that same slap thing, I let go immediatly from the shock.
Is this a legit tecnique? Is it like...taught???
