Heh, not so much that as, if you had, you might know what I’m on about. But then again, perhaps not.
The purpose is to imply an explicit shot with the plausible deniability of being able to say that it’s just someone drinking from a bottle of water. Well, yes, it is. But given the aesthetic context in which the image was created and chosen and distributed, a water bottle isn’t always just a water bottle, and a cigar isn’t just a cigar.
Perhaps I need to do an (err) blow-by-blow to illustrate what I mean.
