What a genius, image-conjuring word! I immediately pictured shady backroom deals and back alley exchanges. Skullduggery only has one meaning. From Dictionary.com:
While listening to KNX1070 last week, during their business segment, Frank Mottek and an expert were talking about one of the many terrible financial situations going on right now. I forget if it was about the housing crisis, Wall Street or oil speculators, but the expert used the word skullduggery.
skull·dug·ger·y or skul·dug·ger·y n. pl. skull·dug·ger·ies or skul·dug·ger·ries
Crafty deception or trickery or an instance of it.
[Probably alteration of Scots sculduddery, obscenity, fornication.]
Really, its perfect when describing what may have happened to bring down our economy. Sigh.
