Academics do not dictate what is and is not a word, usage does and it is generally difficult to find historical usage for recent words.

Edit: mistook what you meant by "academically desperate" most likely but I am not 100% sure about what you did mean by it. New usages have vague definitions since there is not enough usage yet and it may very well be a new way to say "talking" but the definition you gave makes it sound more like a new way to say "discussing."

Edit a tad more:

Did a bit of digging and "languaging" has its first recorded use (according to google books) back in the early 1800s and has had a fairly regular niche usage up until the 1960s where use starts to increase.
