A mixture of anger and curiousity.
Originally defined by Kyle Macdonald in his book when he traded down to a measly snowglobe in his "One Red Paperclip" campaign.
The ultimate aim was to trade up to a house. When Kyle traded from "one afternoon with Alice Cooper", (which was already a step down from "one year in Phoenix") to a
stupid ass snowglobe, evidently, his fans were outraged. If they knew about his secret deal with Corbin Bernsen though, they wouldn't be so outraged at all.
Kyle observed a mixed range of emotions. The two key emotions that he observed were anger and curiousity.
Furiousity was born.
