mundane
n.— «This is my best effort at a summary of Karyn Ashburn’s talk.…On those occasions when she showed up at a con to meet Elise, she saw lots of fans in groups talking. To her they seemed angry and rude. To Elise they seemed nothing of the sort. Observing them more closely, she realized that they were using different social cues, different body language, different eye contact, and even different ways of forming vowels than what she jokingly called “my people,” or what for convenience sake I’ll call mundanes.» —“Fannish Accent? Minicon panel” by Cally Soukup Usenet: rec.arts.sf.fandom Apr. 15, 1999. (source: Double-Tongued Dictionary)
