Sexy foam?

Not Always Right is a very funny site – especially if you have ever had a job that required you to interact with customers in some way – about some of the instances where the customer isn’t, well, right. Few are coffee-related, but this one made me smile

(A woman walks into the coffee shop and orders a latte with “sexy” foam. I make what I thought was a latte with really “sexy” foam.)
Customer: “F***! This isn’t right. I want it with really sexy foam.”
Me: “Okay…”
(I make her another, with lots of really thick foam.)
Customer: “No, no! Sexy foam, really sexy foam!”
Me: “Okay, so less?”
Customer: “No, you know… sexy! Sexy foam!”
(I make her a third drink. This time less foam and more milk.)
Customer: “You don’t get it! I want sexy foam. Really sexy foam!”

I’ve heard people request some pretty unusual things from baristas in coffee shops, but this is a new one on me. I have no clue what sexy foam means, though I would have guessed extra-thick foam, too, if I were on the bar.
