I've never heard of that "training" - however - what could be equally effective as a deterrent would be some urban myths about girls doing such a thing.
If we could get the typical perps to hear these strories - remember we are typically not dealing with the rocket scientist end of the scale here - it could work as a deterrent.
Not to be a conspirator or anything - but I wonder how much societal change we could affect by informal buzz/viral/guerilla marketing using communication tools like the internet.
A good one to start would be about all of the terrible damage girls have been doing biting. It would also give those on the fence in a a situaiton like this a story with which to fight the peer pressure.
