Burke, your fastidiousness would freeze beer.The "boomers" are always talked about in terms that vary little. One thing that you will find in any sociological description of the "boomers" is reference to the Vietnam War, which to us Gen-W'ers is completely moot. That war was over before most of us W'ers were old enough to understand what it was even about.
"Preppies" is a sociodemographic description as well as an age-group description. If you didn't wear Izod sweaters and wear loafers, you weren't a preppy. It primarily refers to attendees of expensive, east-coast preparatory schools (hence the name), or those who tried hard to look-and-feel like them.
So we're still left without a real "generation."
