In Italian, the word “graffiti” literally means Scratchings, or clawings. I imagine that’s what these people were trying to do when they put “graffiti” all over the walls of the pedestrian tunnel.
This person wanted to be mad in English… I give them an A for trying ☺
There’s also a fad going around about “Son Of Troy”
Then there's the classic teenage comeback. "Your mom is Troy".
