Some other recent new words, this time from range of UK sources:
Commentariat - from a report by the Work Foundation (left-leaning think tank), presumably referring to think thanks and the like
Travelista - from the "Spend it" section of the Financial Times (not a left-leaning think tank!), referring to travelling fashionistas
Glamping - from some glossy mag or another, referring to 'glamour camping', the art of paying thousands of pounds for a fluffy pillow and blanket and private portaloos at music festivals.
I know it's not fashionable but I quite like new words like this!
