Hella- very (Northwest-see "wicked")
dope- interesting or good (ex: She was totally dope.")
I cant think of any others right now.

I have also used and heard "wicked" as is awsome, great. "sweet" means the same.

I absolutely agree with both posts and would add the word "tight"

as in, "That's tight," meaning, that's good, etc. It can also mean close or connected, as in "We're tight like that."

"harsh," meaning...harsh, rough, blunt, cold, unfeeling. But you can use it as a verb, as in "You are so harshing on me right now," which means somebody is being really blunt or cold. I'm 23 and I live in Southern California so you can see where this is coming from.

"grill"--someone's face, as in, "He got all up in my grill"

"feel" --understand, comprehend, sympathize. As in "I feel you." It is often said twice in succession for emphasis and can be used in various ways like "I feel that..." and "I'm feeling you." It's another way of saying "I understand what you're going through."

"dog"--friend "he's my dog" and "whats up, dog"
