V.O.A

Vandal or artist?/Vandalism or art?
A tag used in public places often where the vandal's other works have been repeatedly removed. Used to question authority often in places such as a school. While its an interesting concept, it still counts as vandalism.

Principal: It has come to my attention that we have a major issue with vandalism in this school.
Student (hidden within the rest of the students at the assembly): V.O.A?!!
