I was just listening to my favorite podcast - Deeper Shades of House podcast by Lars Behrenroth. In the 2 minute voice intro, he says "Enjoy this. Skin one up. If you don't know what that means, look it up. That's what Google's for."
So I did a Google search and didn't find what I was searching for on the first page. Hmmmm, that's odd. Must be so cool of a saying that even the Googles doesn't know what it means.
After clicking "Next" a few times, I stumbled on some verbiage from this site that makes sense:
Tiger then handed me a heavy sandstone pot. Inside was a roll of extremely thin cigarette paper and some really pungent weed.
"Skin one up," he said.
I
realised that this was the practical part of the interview and that I
would need to pass this test to prove myself as a proficient
pot-manager. Unfortunately, I’d never learnt to roll joints terribly well.
So there you have it... it means to roll a joint. The next time someone's talking about pot, I'm going to throw that phrase out there to make myself look like I'm from the streets. Yeah, that'll work. Maybe I'll add a "bra" in there, so I sound Cali. "Skin one up, bra!"
