A way to indicate that you are from Northern California, but not fake Norcal, like the Bay Area, but real Nor Cal, as in the emerald triangle or above. Also the most effective way to get So Cal people annoyed after they ask where you from. REPRESENT!
"Where are you from? Wanna smoke this blunt?" So Cal guy
"Hella Norcal. I only smoke good weed, not socal shit." Norcal badass
