h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

There is already an article on South African jargon here: A4351402

Here is another site with a bit more: http://banananewsline.wordpress.com/about/a-handy-guide-to-speaking-south-african/

Give it a look, and perhaps look over the rest of the site also! That slang is legit, but the rest of the site is mainly satire (with a huge dollop of truth as well though as I can vouch, living here). But I see many of my fellow South Africans still don't understand satire, I've seen articles linked on Facebook treated as if they were straight news! There are quite a number of such sites around these days and they do seem to catch out quite a few folks.
