Graffiti is "...a pathetic attempt to emerge, to be visible..." said one of the talking heads during a short video clip on the problem of urban doodling and scribbling in Rome.

Tropical colours in a wan, mid-Atlantic setting in that respect.

At the same time, you would be able to hear my teeth gnashing on another planet if I went outside and found a giant, randomly shaped tag, zig-zagging across the sides of the building I live in. Remember I'm a Brit, and all of us carries a strain of nimbyism. Mine might be detectable only at trace levels, nevertheless it's still there.

Where I do stand back and wonder is just what do some slogans mean. Is there a meaning even?

Let's get the common ones out of the way first. Applying the first law of Rumsfeld, then we know what we know, which is: political are easily understood; same goes for territorial boundary marking - W10 posse rulz this 'hood, for instance; love and heartbreak, straightforward enough, maybe too much in cases; and finally, the public address to the football team is as direct and explicable as the rest.

But it's the other category, the head-scratching, the arcane, the mysterious. What for instance, just what, did this graffiti artist in Doncaster, have in mind when they were spraying " Albert, the kid is ghosting" ?

Who's Albert and should his kid be ghosting, whatever that is? Answers, please, on a postcard. I've tried already back in May, when I first spotted it. I've no idea
