Learned a new word - although I doubt that I can pronounce it, at least I know the correct context: Schaudenfreude is German meaning taking pleasure in the misfortune of others.
I guess the modern, internet version is lulz; which is fun at someone else's expense (especially when it relates to trolling)
A New York Times article in 2002 cited a number of scientific studies of schadenfreude, which it defined as "delighting in others' misfortune." Many such studies are based on social comparison theory, the idea that when people around us have bad luck, we look better to ourselves. Other researchers have found that people with low self-esteem are more likely to feel schadenfreude than are people who have high self-esteem.
My observation of the Schaudenfreude phenomenon - when it comes to overblown celebrities and notorious villians that are deserving of their downfall - it'll be around for a long time.
