Since when did Hell become an adjective?
"Dat was hella sick"
by Raddichio February 15, 2005
The word is hella sick, it originated in Northern California in the bay area. Its used for hella things, you can use it for pretty much anything, just read the conversation:
Me: Dude, that party was hella sick last night.!
Tom: I know, there was hella people!
Me: I know you got hella drunk dude
Tom: I passed out hella early, when I woke up this morning I felt hella bad bro. I threw up hella times
Me: Dude you didn't even drink that much! I had hella beers and was up hella late!
Tom: Fuck you dude your hella annoying!

The term hella, as aforementioned herein, indeed originated in NorCal (some would speculate San Francisco, to be exact), yet 'hella' essentially derived from the phrase "hell of a" as in: "I've got a hell of a headache." Or: "That's a hell of a hike from here to there." Thus, throughout time, the phrase "hell of a" inevitably condensed to "hella" as we so frequently hear it used today.
"Yo! The new Tech N9ne album is HELLA tight!"

Cite source: I was present & used the term "hell of a" as the phrase developed during its evolution into "hella." I really have never used "hella" as it's more of a younger generation term. One of my friends from years gone by, however, did used the term during its evolution period which came out as "helluv" (hell of w/o the "a") before "hella" fully caught on. He'd say stuff like, "That's helluv cool!" Quite unique, the evolution of the American English language, wouldn'tcha say?! ;) ~slangity-slang-she-bop!

Cheers! :)
