A lot of rich Fresnicks (Fresno people--I was born there and just wrote a book about the place) own second homes in Pismo, so giving them a seemingly derisive moniker (sounds like Bolshevik, yes?) is biting the hand that feeds them and their fancy tax base. I take it “Bakos” means “people from Bakersfield.”
Do you have a citation for “Zonie,” a San Diego term for people from Arizona? People on the west coast just can’t get along.
