I love to watch for the new entries in the Merriam-Webster Collegiate Dictionary.  It usually reminds me of my cultural awareness (or lack of awareness).  Of the nine new words added, only one was unfamiliar—parkour which “is the sport of traversing environmental obstacles by running, climbing or leaping rapidly and efficiently.” (My kids were doing that decades ago but I thought it was just playing outside.)  Now I know! The other words were: boomerang child, bromance, crowdsourcing, fist bump, helicopter parent  robocall and tweet.  See the full article http://prnt.in/ZSK
