Capitalism and socialism (elections anyone?), democracy, globalization, marriage, bigot, meme, touche, schadenfreude,and professionalism.
The word meme is courtesy of Richard Dawkins, noted geneticist and atheist, who coined the term in 1976 to denote a unit of cultural information and gave us a way to talk about piano playing kitties and ehrmagerd and all manner of other crap.
Touche, Dawkins.
