Flavor Of the Month

I've recently seen the phrase "flavor of the month" used to put down a component. While it clearly implies that the subject product doesn't have staying power or won't deliver long term satisfaction, it's my observation that a component has to be pretty darn good to attain FOTM status. Sure there's an element of hype, but internet forums such as this one are excellent at separating the real deals from the pretenders. Can anyone name a component that was the Flavor Of the Month that turned out to be a turkey?
