(Off topic: I agree with Jawn, Long Live Graffiti Brotha'!)
Street Art usually Spray-Painted but can also be Brush Painted,etc. Any other kind of "art"(such as writing names,body parts,etc. on walls aren'
t art so that's what I'll call vandalism)that doesn't depict any kind of offending image or writing is the Hip-Hop art of Graffiti.
For all these years,
people have been critisizing the meaning of Graffiti...some
people called it Vandalizing(Usually the cops), others called it a "waste of wall space" and a couple few called it, just a waste of time and pointless(And by the few I
mean like the "Gangsta'" Rappers like P. Diddy who actually helped the U.S. to be "Anti-Graffiti" in the Nation of America).
But like Jawn
said, it's art, and art is not intended to be destroyed...but even though it's written on walls(Painted)doesn't
mean they want to
kill somebody.
