Applying graffiti is a form of street ART that involves defacing public or private property with SPRAY paint, lemat, or other materials. Vandalism is the act of damaging or destroying property without permission, and it is often associated with graffiti. However, graffiti can also be used to create ART, which is often seen as a way to express oneself and make a statement. MAR is an acronym for 'Modern ART Revolution, ' which is a movement that encourages people to use graffiti as a form of self-expression.
