This is a variation of the old and tired bit of husksterism, which

My standard translation sources do not even list that word or similar ones.

I'm not sure what Bryan means either. I think he may have conflated a couple
of different words:

"husker" -- one who husks corn (removes the outer husk to get to the kernels)

"hustler" -- one who hustlers, a shrewd and unscrupulous person who knows
how to get around difficulties, usually implying that they are a confidence
trickster ("con artist")

The "-ism" suffix creates a noun, in this case, the state of being a
"huskster", whatever that is supposed to be. Hustler?
