Typically I cover graffiti that has a message of some sort in “Street Art Dispatches,” but with the above piece of graffiti, there is no particular message. But it’s hilarious, and makes me wonder if people actually do lick back sweat, and, of course, what the attraction or turn-on of such an act is. I know there are foot fetishists, musk smellers, asphyxiophiliacs, fart sniffers, coprophiliacs, tree fuckers, and so forth.
