Been tried on me but well, it can be blocked. And the woman attempting that on me like the guy who did? It only works when you got surprise and I do indeed hit like a truck when I connect!
The one and only time I got caught like that it was a breathtaking experience. But strangely I still was able to do my share of damage in retaliation so unless you really can connect HARD all you will do is piss off who you are trying to stop.
Ladies, if you really have to defend yourself don't risk a savage beating, Use your fingers and drive them right in his eye sockets and shove your thumb right into his nostril as hard as you can and grab his face like a bowling ball. The other free hand grab his nuts and squeeze with everything you got. If you feel them pop in your hand you just caused a man pain so intense he is going to the ground. Any blows you suffer will be him trying to get you the hell off of him. And when he does he will not see shyte or be able to breath at all. Then pick up a nice heavy object and pound him a few times. Break some ribs unless you got flat sole shoes and want to kick him a few times, maybe stomp him good. THAT IS HOW YOU WIN A FIGHT WITH A SUPERIOR OPPONENT! likewise why risk getting the beating of a lifetime?
Now a martial arts girl, a warrior woman as it may be,
I don't need to tell you squat! You women KICK AZZ! You know how to cause hurt!

You are way too cool for the world...
Why bust a man in the nuggets when you can just take your time and inflict painful boo boos generously ALL over an offending male's body? Nothing is as embarrassing as a guy getting his posterior handed to him by a girl!
Thugs can't handle being thugged on by someone they thought was weak.
