From Ordinary World 2016:
Hey, today's my birthday, man.
Um, and I'm thinking about having a party,like a daytime blowout kinda party.
So... Yeah, dude, um, as soon as you get this, or...
I'll call you back. As soon as I get a location, I'll call you back.
It's gonna be sick.
Is "It's gonna be sick." an idiom? or is it a common expression?
Thanks a lot
