I thought it was a loop shot around and over the top of an extended arm from the outside position.
MAybe that was called the bolo shot i think ,different shot.
I like it anyway, cause the arm covers the intent of the shot and so it can be a ko shot from seemingly out of nowhere.
Ive used it against taller opponents too. that have a long jab that they made the mistake of holding out there too long for control.
You can even switchfeet under neath that arm by going forwards and under with your head taken there by your rear leg heading out on a 45 angle as you pull the left foot back around into stance as you land the right over hand bomb over his left arm. (its safe to switch there in that spot,actually gives you a power advantage).
