I've heard an urban substitute for your "wicked" with "mad." I heard some people in Baltimore, some people in DC, and certain parts of NY and Jersey say it.

Example: "Man that party was mad crazy."
Translation: The party was really wild, but in an enjoyable sense.

I've heard some people from VA used the same meaning but use the term "hella'. "

Example: "It's hella' lot of food up in here."
Translation: Large quanties of food are in the room or space.

Others I've heard/familar with:

Example : "Yo, this spot is packed!"
Translation: It's very overcrowded in the area.

"Dat outfit is tight. You gonna' look mad fly."
Translation: The person is complimenting on someone having a nice outfit, and says that they will look really good.

Translation: " No one on da' corner have swagga' like us "
Translation: A comment about orginality. No one has style, quite like this individual, or group of individuals

Example: "You ain't a G man, you a wangsta'. You ain't down wit da' game."
Translation: The person is issuing a "g -check." Questioning the individual's street credibility, awareness of "the hood", gansta' life, etc.

LMAO! I had forgotten about "mad" and "hella."

MAD CRAZY

HELLA COOL

My friends from NY used "mad" a lot to modify adjectives. "Hella" never really picked up, though some people tried.

Hella is used a lot in the south west of England in Cornwall.

Yeah, I use mad crazy. But I hadn't heard hella til I made friends that moved up from Southeast DC and Va (and further down I assume) and their starting to blend their "southern-swag slang" as I like to call it, with ours.

They also say fixin' and/or fitna' as a verb for about to, getting ready to, etc.
