Lubricious: having a smooth or slippery quality; characterized by lust. As in, "The snake-like used car salesman was downright lubricious in his sales and social tactics and it made his customers' skin crawl."
As a former employee of a car dealership, I can confirm that lubricious is the perfect word to describe the stereotype. Oh, the stories I could tell you. The snake here is wearing creepy old man salesman glasses. The two are tied together, if only in my head.
On a side note, the format is a little different this week. My drawing app has been on the fritz and it's only a matter of time before my $500 first generation iPad becomes a $500 recipe holder. So I kept the drawing simple and fast, because I didn't know when the app would crap out on me. I kinda like it, but I don't want to be totally forced into it by technology limitations. Watch, next week this will be a scanned in pencil sketch with crayola marker coloring and then I'll really be whining about my technology limitations.
