How 'bout “State of Calfusionâ€.
This has the double meaning of fusion of 2 things and feeling confused (about where one lives in this case).
Works well as an answer when someone asks where you live.
This applies to me as I live in San Clemente and have friends in San Jose and used to live in Marin.
How about Sonofornian.
How about yo-yo-cal? or shorten that to yo-cal?
Regarding the lady who splits her time between so-Cal and nor-Cal (no-cal sounds like a diet drink to me), how about pan-Californian? I think this issue is somewhat specific to California because, although it's one state, it has two distinct cultures. And besides, how can one be verti-Cal and laid back at the same time?
By the way, what is a “dot orgyâ€, and why wasn't I invited?
Canadians who live in Florida or Arizona durring the winter months are known as "snowbirds" So perhaps one who travels up and down the state of california could be called a... "sonobird?"
