It's like the list of impossible acronyms (anyone flown a supplier's ILS?). I once phoned a guy up because I had no idea what he was on about in his letter; turned out, neither did he - he was just passing on an unintelligible message. Speak plain English or shut up! However, if you're drafting a letter for a 2-star or higher, never miss up on the opportunity to drop an "onageristic estimate" into the text. I've had 3 of them sign it off!
