Jack-Smack

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.

Jeff: Hey Greg, Jimmy owes me some money and I asked him to pay me and he laughed.

Greg: He laughed?

Jeff: Yes, he laughed!

Greg: You need to Jack-Smack him and let him know you are serious without knocking him out.
