What is a "Slovenian Cadence"?

Question

I recently acquired a large collection of music theory review materials. In it, I came across the term "Slovenian cadence." Does anyone know what this might be? Unfortunately, the review materials came from an untold number of sources acquired over several years (if not decades), and there's no way of identifying who it was that actually used this term. Online searches for "slovenian cadence" only seem to provide results for Melania Trump's speech patterns (!). Does anyone know what this might be? I have *never* come across this term anywhere else.
