Graffiti art as a term refers to images or text painted usually onto
buildings, typically using spray paint.
Graffiti can be understood as antisocial behaviour performed in order to
gain attention or as a form of thrill seeking, but it also can be
understood as an expressive art form. Derived from the Italian word
graffio (“scratch”), graffiti (“incised inscriptions,” plural but often
used as singular) has a long history.
However, it is often seen as illicit production and vandalism asset. For
instance, removing graffiti or restricting the practice of graffiti from
the public space has been a controversial issue for artists and
authorities.
