Locals Vs Cross-fandom Commenting?

2.0BRAINROT SCORE

LOCALS— ORIGIN, MEANING & USAGE

Locals In fandom talk, people outside a particular online fandom, who do not know its in-jokes, history or norms. Used neutrally to mark the boundary between fans and everyone else, as in "explaining it to the locals"; the exact usage varies by community.

Origin:The Wikipedia page for a site called Locals returned HTTP 404, and Wikipedia's fandom article does not use words for outsiders such as "mundane". No opened page documents this sense of "locals", so the entry is thin and conservative. Fandom communities have long had words for outsiders, but this one has no dated first use that could be confirmed here. The existing entry on stan Twitter is a related community where such boundaries were discussed.
