39/Smooth 

39/Smooth is the very first album of Green Day. Which most, but not all, of their fans now don't even know about.

It was combined with EPs 1,000 Hours and Slappy to make 1,039/Smoothed Out Slappy Hours, which is also not that known but is getting more known because they play a lot of their songs from that album again.

Person 1: Hey, let's listen to At the Library by Green Day.
Person 2: I didn't know they had a song like that. From what album?
Person 1: It's from 39/Smooth- their first album.
Person 2: Huh? I thought American Idiot was their first album.
Person 3: I thought 21st Century Breakdown was.
Person 1: Well, now you know it isn't.

39 Smooth 

Someone who is always there, and with everyone, a social butterfly, but never loses his cool, just plays it smooth more than all the time. So much so he/she is cool 39/24 hours per day.

See John over there?

Where?

By the keg.

Oh yeah, he's just playing it cool.

yeah, 39 Smooth if you ask me.
