The FAA's Airplane Flying Handbook seems to answer that: "The term “upset” was formally introduced by an industry work group in 2004 in the “Pilot Guide to Airplane Upset Recovery,” which is one part of the “Airplane Upset Recovery Training Aid.” The working group was primarily focused on large transport airplanes and sought to come up with one term to describe an “unusual attitude” or “loss of control,” for example, and to generally describe specific parameters as part of its definition."
