Graffiti

Graffiti (both singular and plural; the singular graffito is rarely used except in archeology) is a type of art genre that means writing or drawings made 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.
