Given that today's students are from a much more representative demographic than twenty or thirty years ago, the slang is not really limited to just the upper middle classes any more, and now draws on much more eclectic influences - Caribbean patois, US teenspeak and TOWIE - so it could be argued that what students speak isn't really their slang at all. Then again, there are some examples - BNOC and chundergrad - which seem fairly restricted to campus life, so do seem to fit a strict definition of student slang.
And while we're on the subject of slang, a really excellent new book called The Life of Slang: A History of Slang
by Professor Julie Coleman of Leicester University, is definitely worth a read for anyone thinking of investigating the topic further. It's funny, informative and frankly possesses a level of bare teckers that is hard to match in this field.
