Methinks someone isn't really doing this and is just theorizing (incorrectly) about what is supposed to happen. As someone who has taken (ending up the the hospital once) and given a few groin shots for real, I can tell you the reaction is definitely not to pop back up.
That's exactly what I was saying.
And sure, you could imitate it, but it's still not going to be with real energy, as we can get from hung-le's mistaken assumption that the opp is just going to stand up straight again.
its safe to say that I train some martial arts. Im not that good really, but most people really suck, so I feel ok about that - Sunfist
