My vote for dumbest fad would be using business tropes on rank and file employees and, worse, clients. No rank and file employee wants to be a 'brand ambassador' and clients don't want to rate your 'sense of urgency'. Keep the jargon with the specialists in the back room. The trick is to do important things that might be described by cringeworthy jargon without letting on that is what you are doing! It's like announcing at a singles bar that you are there to get laid when you walk in the door. Everybody knows but its a terrible thing to call direct attention to.
