[ SLANG ][ FANDOM_BEHAVIOR ][ NOUN ]
The gradual growth of fan-created lore additions being widely accepted and reused across a fandom, even though none of it is officially canon.
REAL-WORLD EXAMPLE
"That fan theory kicked off a whole fanon expansion, now half the fandom treats it as basically real."
LORE & ORIGIN
Extends 'fanon' (fan-created, non-canon lore) with an explicit growth framing, borrowing 'expansion' the same way other dictionary terms describe organic content growth.
