Recently while browsing the Web I came across UrbanDictionary.com, which is sort of a wiki of contemporary slang. I found some of the newer words listed there amusing, like "hobosexual" (the opposite of metrosexual; someone who cares little about their looks), "consumerican," ("a particularly American brand of consumerism"), and "wikidemia" ("an academic work passed off as scholarly yet researched entirely on Wikipedia").
Then I came across a word that put me into a more thoughtful zone: "slacktivism."
"Slacktivism" (alternative spelling "slactivism") is a fusion of the words "slacker" and "activism," and UrbanDicationary.com defines it as "the act of participating in obviously pointless activities as an expedient alternative to actually expending effort to fix a problem." It refers to ersatz acts that people perform that they have somehow come to believe are full of meaning, like slapping a magnetic ribbon on your car to "support the troops," wearing a colored rubber wristband to "fight cancer," or refusing to buy gasoline on a certain day to protest high gas prices, instead of, say, actually changing your lifestyle to use less gas.
