While on some level, we all know that language is constantly evolving (remember when e-mail had that pesky dash in it and saying "I'm working for a startup" had people saying either "huh? or "I've heard of them" when you hadn't said the name?), it's great to see that the de facto keeper of all words, the Oxford English Dictionary has added some real gems, including Bollywood (Indian film industry) and my personal favorite, Mullet (1980s haircut, tipped for comeback).
