Graffiti, form of visual communication, usually illegal, involving the unauthorized marking of public space by an individual or group. It can be understood as antisocial behavior or as an expressive art form.

Graffiti (singular graffiti or graffito, the latter only used in graffiti archeology) is writing or drawings made on a wall or other surface, usually without permission and within public view. Graffiti ranges from simple written "monikers" to elaborate wall paintings, and has existed since ancient times, with examples dating back to ancient Egypt, ancient Greece, and the Roman Empire.

Depending on who you ask, graffiti is either a form of vandalism, or a form of art —or both, simultaneously. By definition, graffiti refers to markings, photos, words, initials, or drawings that have been spray-painted, sketched, or even scratched onto walls, sidewalks, or any other publicly accessible areas.

Graffiti, in simple terms, refers to the vibrant and often unauthorized art form that adorns public spaces with colorful and expressive designs. It serves as a powerful outlet for artists to convey messages, emotions, and perspectives. When seeking words to describe graffiti, “dynamic,” “bold,” and “visually captivating” come to mind.
