 == Jaffa Cinema advertisement Origin? == 

 Can anyone verify the time in which ""Jafa"" or ""Jaffa"" came into use and also where it originated from? I am under the belief (until proven otherwise) that the term emerged when advertisements at picture theaters (cinemas) starting showing advertisements for the ""Jaffa"" chocolate confectionery before the screening of movies. This advertisement clip featured a picture of Auckland city after which a huge Jaffa is dropped down to squash part of the city coinciding with a farting sound effect. I believe this advertisement was circulated in picture theaters in Auckland (and perhaps also around the country?) in the early 1990's. I believe after this point Aucklanders became to be known as Jafas/Jaffas by non-Aucklanders and acronyms such as ""Just Another Fucking Aucklander"" and/or ""Just Another Fuckwit From Auckland"" came after this point. There is no mention of these things, especially the cinema advertisement, in this article."
