This term refers to a hoax contrived by Allan Sokal, showing the meaningless of much academic writing in literature and the humanities. Following is a short extract providing a little more information. There is easily accessible information under Sokal on the web.

-----------------

A gloriously devastating expose of all this was recently delivered when an impressively scholarly and difficult article was published by the prestigious academic journal Social Text, but later revealed to by its author Allan Sokal to have been a load of deliberately constructed meaningless rubbish. (Sokal, 1997) Just as well he said so --or no one would ever have noticed!

Predictably a thriving academic sub-industry has since grown up interpreting the event! (Roberts, 1997/8, p. 24.) One is reminded of the celebrated painting later revealed to have been the work of chimps, without interfering with the on-going scholarly debate about its artistic merits. As Kamiza says, the paper"...which is arrant nonsense, is quite literally indistinguishable from a thousand others." ( Kamiya, 1998 .) Sokal said later, "My article is a melange of truth, half truth, quarter-truths, falsehoods, non-sequiturs, and syntactically correct sentences that have no meaning whatsoever." (Sokal, 1996.) "It took me a lot of writing and rewriting before the article reached the desired level of unclarity." (Mukerjee, 1998, p. 18.)

I do not think Sokal himself draws the most important implication. His concern is to reassert the validity of the modernist quest for objectivity in some sense, especially through restoring respect for scientific knowledge, and to return the Left to that quest. (Mukerjee, 1998, Sokal, 1996.).) His central concern seems not to have been to expose and ridicule the trade in meaningless, pretentious, deliberately obscure verbiage, and the widespread corruption of intellectual activity and waste of time its general uncritical acceptance has caused. Indeed it is somewhat disturbing that he identifies the fault only as "sloppy thinking", when it is much more serious than that.
