"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 it's much more than that. It's 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. It's a symbol. It's a way of life. Hella.

You just use it cause it's a term that you grew up in the neighborhood saying. It's 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."
You're hella dumb.

The farmers from Northern California who settled here a long time ago (probably before the 1950's) were patient and slow people and took everything with ease. When they communicated to explain "VERY" they would say "hell of a" instead of "very" or "a lot". Then the city folks who migrated in later to the Bay Area took the Northern California farmers saying and shortened it to "Hella" instead of "Hell of a."
So in the end the word "hella" comes from the Bay Area city folks. Short and sweet.
She/he was hella sweet.
