Academic Wank describes a writing method employed by students of any subject, (but especially psychology,) who may not necessarily have all the facts at their fingertips, but need to pad-out an essay with some generalised waffle in order to meet the minimum word-count requirement for the coursework set. Often used most in the early hours of the morning before a deadline, academic wank must be employed alongside content with actual intellectual merit in order to not result in a fail. Requires less research than an essay that will get you a first class degree.
"The research methods essay? yeah, I didn't use enough references really, but I typed out some academic wank and handed it in anyway."
