JimL sez, "Originally published in the July 1922 edition of FLAPPER magazine, this dictionary went into some detail, listing the group's slang and providing definitions. In the process, it also provided an insight: through the slang we can begin to discern attitudes and priorities and the mindset of the adherents. And the adherents, after all, were our grandmothers and great-grandmothers. Who knew?"
