Essentially, the Sokal Hoax refers to an article, written by a legit academic and submitted to a peer-reviewed, post modern, academic journal. The published it, and it drew all manner of praise, whereupon the author spring the gag - it was all gibberish, intended to specifically poke fun at the jargon-laden, pretention that is (all too often), PoMo academia. It made a big kerfluffle, and everyone was aghast, and nothing really changed. (There's even a post modern generator, if you'd like to craft your own meaningless theoretical garble: http://www.elsewhere.org/pomo/.)
But now, in response to the trend in theology towards an almost post-modern jargon-fest, typically aimed at harmonizing science and religion, a scholar has perpetrated his own 'Sokal-style' hoax. He cooked up a long blob if impenetrable gibberish, submitted it to a few Very Serious Theology conferences, and despite having offered up essentially word soup, was happily accepted.
