Graffiti is art that is written, painted or drawn on a wall or other surface, usually without permission and within public view. Graffiti ranges from simple written words to elaborate wall paintings, and has existed since ancient times, with examples dating back to ancient Egypt, ancient Greece, and the Roman Empire.

Hip hop or hip-hop is a culture and art movement that was created by African Americans, starting in the Bronx, New York City. Pioneered from Black American street culture, that had been around for years prior to its more mainstream discovery, it later reached other groups such as Latino Americans and Caribbean Americans. Hip-hop culture has historically been shaped and dominated by African American men, though female hip hop artists have contributed to the art form and culture as well. Hip hop culture is characterized by the key elements of rapping, DJing and turntablism, and breakdancing; other elements include graffiti, beatboxing, street entrepreneurship, hip hop language, and hip hop fashion. From hip hop culture emerged a new genre of popular music, hip hop music.
