so…what does zhush mean anyway? Its a verb, and urbandictionary.com defines it as thus:
zhush or joosh

zhush (as in the French je + “oosh”) is a word whose usage dates as far back as 1968 in Britain. Its spelling, much like its origin, is elusive. It has been defined by the American Dialect Society (who placed it on their 2003 Word of the Year List) as a verb to mean “primp or fluff up”.
Personally, I like to apply it to all things style related. Like, “let’s zhush up this tired room with some new throw pillows.”
