Ain't the internet great?
I looked at that, too. It was, apparently, popular from the 40-60s, fell off some, and has been rising (SWIDT?) since the 80s. I guess "new" was a poor word choice, but it has increased in popularity relatively recently, which would explain why I hadn't heard of it until not too long ago.

Could be. I don't recall hearing it until the last half decade or so, maybe a little bit earlier.
I also wonder if it's socioeconomic. About.com seems to think it has its roots in prep schools, and I have never run with the prep-school set. Oddly enough, the first time I heard the term (and the bulk of the usage I see now) was in reference to sports.
Could be a blend of both, too, since the prep school thing has a regional component.
