What does “Quomodocumque” mean?

It means “after whatever fashion.” I didn’t learn this in school — my high-school Latin stopped somewhere around “Petrus Cuniculus in arbo cum eius tres fratribus, Flopsus, Mopsus, Cottontalusque habuit.” I saw it on a slide in a history-of-mathematics lecture and had to go find out what it meant. Emmanuel just pointed out to me that, while “quomodocumque” hasn’t yet made it as an English loan-word, the OED does have the related “quomodocunquize,” meaning “to make money however one can.” The most recent cite is 1652, but in these near-recessionary times, quomodocunquizing — or even all-out quomodocunquism — may be poised for a comeback.
