If you have enough space to slap their ears, then why not just punch them in the side of the head? Surely a punch is much more effective, and it won't land you in jail.
I really think that you need to look at the questions you're asking, as you seem to have some misunderstandings going on here. First off, what makes you think that a punch will not land you in jail? Second, the slap does not require the hip rotation as the punch would.
Out of curiosity, what arts do you study?
