Any word used by California residents that seems foreign to the rest of the countries English speaking folks, Like he/she /I/they was all, Hella, Hyphy, Skyeing, Ghost ride the whip and many more.
Word like Fully, Fist pump, GTL and other Non west-coast Rooted terms of Urban Hippie Slang does not fit into this definition.
Hella dudes are gathering to watch the girls fight,
I was all like Hey Fuylly is not California slang you and that term go back to the east coast,
King of the super duper Hyphy Hyphy.
So I was ghost riding the hip and I saw a cop so I just walked away and pretended the car was not mine
