vaping blu smells good

I'm admitting how old and out of it I am: I didn't know what "vaping" is until I saw an advertisement in Rolling Stone for an e-cigarette called "blu" (lower-case, no "e"). The title of this collage was the tag line over a photo of a young woman vaping with the product—a black tube with a shiny blue cap.
