OPA (Obsessive Possessive Aggression) is an artistic collaboration whose focus is researching the social, cultural and everyday issues, as well as ways of looking, thinking and behaving of certain community in the shifting social and political conditions. In doing so, OPA questions the various social habits related to forming the individual and national cultural identity, and on the other hand stereotypes built by forming the identity.

OPA reacts to the actual situations conceptualizing them into an art form by meta-situations/positions/narratives. Thus their activities include actions, context-specific projects, video, TV screenings, mockumentaries, etc. Their projects are often related to the societal life of the artist and the art system, deconstructing the artwork on its units: artist/performer, object/artifact, audience, expectation, and more widely, curator/manager/institution.

OPA's most used topics so far are authority, intrusion, elitism, conformism, lethargy, ideology, utopia, and media manipulation.
