Oh yeah, 'wicked' is a wicked great adjective. I'm sure Stinky knows all about pahkin' her cah haha.

Some more random slang off the top of my head...

What's the deal?/What's good? - What's up?
Zip - Ounce
Shitfaced/Hammered/Shattered/Wasted/Wrecked - Drunk
Zapped/Snapped - charlie high

Those are probably common though...here's a good one that we say...

Auto-Pilot - Being so drunk/fucked up that you are there physically, although making rash decisions mentally. Kind of self explanatory but hard to explain in text.

Can't think of any more right now...but I know there's a lot more.
