An open handed, back-hand slap to the temple. Not intended to knock someone out, but instead, to make someone appreciate your point of view in a forceful manner so they eventually agree with you. This is considered a more intimidating and more painful form of "Point Making" as opposed to the more traditional and less painful open hand cheek slap.
