Corollary to the meaning of "english" that has to do with puting enough spin on a ball to alter its trajectory is the related term "body english" whereby a person's bodily movement after releasing a projectile is performed in hope of influencing the direction of flight. Also known as "follow-through." Further thoughts?

All that other ethnic and geopolitical stuff, I'll leave to others. It's interesting enough, but I have nothing to add...
