"fun"
When writers (they call themselves writers since graffiti originated from leaving their names) are asked why they do the graffiti, an undertone of ‘fun’ lies behind. As a matter of fact, kitsch about pop (not pop art but the entire public media) is permeated in graffiti art over all. The unbearable lightness of scribbles begun with mischief is the kitsch motive, and the fact that they understand doodling to be illegal but legitimize the action is the same as the attitude exhibited by kitsch.
In the end, graffiti is not a simple image style but the attitude and value. At this point, it is too serious to be regarded as fun. It is light not because it is kitschy, but because the graffiti writer’s attitude of dealing with the world is graffiti itself. That is right. This graffiti you are looking at is our ‘serious fun.’
