What Does This Mean?
[ SLANG ][ BOOKTOK ][ READING CULTURE ]
Showing off having discovered or collected an older, out-of-print, or lesser-known book before it got a viral BookTok resurgence, treated as a form of reading-taste credibility.
REAL-WORLD EXAMPLE
"I had that book on my shelf two years before it blew up, full backlist flex."
LORE & ORIGIN
Combines publishing's 'backlist' term (older titles still in print) with 'flex,' naming the specific BookTok bragging pattern of having found a book before the algorithm did.
