👉 Graffiti is a type of art or writing that is painted on walls, buildings, and other surfaces using spray paint or markers. It is often used to express political messages, social commentary, or personal feelings. Graffiti can be done by anyone with the necessary tools and materials, but it is commonly associated with those who are part of the punk rock subculture, which emerged in the 1970s as a response to the government's attempts to control rock music.
