The uncomfortable and frustrating act of having to make conversation with your pot dealer instead of just paying and leaving.
Common topics include: World peace, how it's "bullshit" that weed is still illegal on a federal level, Ron Paul, Hootie & the Blowfish, how "brilliant" The Big Lebowski is, etc...
"Hey, I thought you were gonna be right back."
"Yeah, I stopped over at Manfred's for a dimebag, and had to give him lawn service for like 2 hours."
