[Rihanna]

Term used to indicate personal superiority. When spoken in conversation, the receiving party immediatley knows that the person saying the word is of a high class because of that persons NorCal roots.
Thusly, if the receiver is not of the same geography and stature, negative emotions arise from envy. A primary example is that of the frustrated SoCal dweller who is frequently subjected to the mighty and humbling presence of NorCalers.
Alternatively, Hella can alert other prestigious NorCalers that they are dealing with a higher species much like themselves.

Hella is an all-purpose word. It has its roots deep in the soul (I meant to type soil, but soul works here too, haha) of Northern California. It means something along the lines of very or really, but its much more than that. Its not just a word, but a statement of cultural identification, of a long-standing bond of trust and respect for fellow Northern Californians, and of a mutual understanding between you and the rest of the world that you are from (or, in the case of anyone who has lived with kids from NorCal, that you are an honorary resident) NorCal. As the subtle innuendoes of the word can only be understood by absorption, one must experience and be engulfed by it (as Northern Californians are from birth) to truly understand when its usage is appropriate. Hella is a word. Its a symbol. Its a way of life. Hella.

You just use it cause its a term that you grew up in the neighborhood saying. Its like being from Pennsylvania and saying youse instead of you. Hella originated in the [bay area] like hella years ago. It was just something that grew on you and you still use it today cause you never grew out of it. Some guy from Vegas tried to tell me [hella] started in Vegas and I was like Fuck that. Dude you gotta be fucking retarded, hell no.

[Donald Trump]

Maximally quantifying term; originated in Northern California.
