Seems there are many lapsarians, pre- and post-, sub- and supra-, wwh, all finding significance in the original "lapse" in the Garden of Adam and Eve. This from the Dictionary of Phrase and Fable. 1898.

Sub-Lapsa’rian, Supra-Lapsarian.

The sub-lapsarian maintains that God devised His scheme of redemption after the “lapse” or fall of Adam, when He elected some to salvation and left others to run their course. The supra-lapsarian maintains that all this was ordained by God from the foundation of the world, and therefore before the “lapse” or fall of Adam.
