we have sooo many in ny

"MAD" is prob the most popular and used in like every sentence around here haha.. it means "very" or "sooo" : "I was mad high" = "I was so high" (sry someone said this before heh).... nobody on long island/nyc says "WICKED" but ive heard of that one before from other states and england too

SICK- someone mentioned this one.. it means the same thing here.. cool

SWEET- im pretty sure everyone knows what that means.. i dont even know if its really "slang"

ILL- i havent heard this one on here yet. It means something cool, fun or w/e
example: "that concert was sooo ill", "thats fuckin ill"

BLITTED- just means fucked up.. i dont use it that much but some people say it.

WORD/WERD or WORD UP- if you know what "Tru" means as far as slang goes.. this is like the same thing.
example-
ted: i'm going to chill at the bar tonight
joe: word

TRU/TRUE- works the same as "word" pretty much.

wow ok thats all for now haha.. those are the most popular, but id say "MAD" is used mad (hah)
