The term "BeBop" was coined by the trad jazzers as an insult to the modern jazz player's and their music. They took the term and made it their own. Funny where some things start and where they end up.The 'Youth of Today' just seem to cherry pick music from all eras, mix it together & think they have something 'new'.
They don't seem to know or care where or when it originated.
That's why there has been no teenage musical movements since Grunge. And it was named by a British journalist!
And even then, what were the fans? Grungers, Grungists, Grunge Rockers?
