California speech splits north and south and exports slang to the rest of the country. Northern California says "hella" for "very" ("hella good"); Southern California puts "the" in front of freeway numbers ("take the 405") and gave the world "gnarly", "bomb", and surfer and Valley vocabulary. Coastal weather brings "June gloom" and the "marine layer"; "the Bay", "NorCal", and "SoCal" mark identity. Spanish runs through it everywhere. Trend-driven and media-amplified, California slang often becomes national slang.
California slang includes "hella" (very, Northern California), putting "the" before freeway numbers like "the 101" (Southern California), and surf and Valley terms like "gnarly" and "bomb". Much of it spreads nationwide through media.
"Hella" means "very" or "a lot of" and originates in the San Francisco Bay Area — "that's hella cool", "hella people". It is the clearest marker of Northern California speech.
In Southern California, freeways take a definite article — "the 5", "the 405", "the 101" — unlike most of the country, which drops "the". It is a reliable SoCal tell.
