Yep! Ive been paired with a couple of guys in training where we were taking turns, throwing and blocking headkicks and the guy was blocking with his elbow 'it killed my shin' but when I realized he wasnt gonna stop doing it, I started throwing under and over his elbow to rattle him. If hes gonna be a dick F him. Those guys never last anyway. Most people that cant play nice with people always quit.
good way to catch this kind of stuff is to go over and down - if the flexibility allows
