culture jamming 

An act of vandalism carried out by uneducated but highly indoctrinated activists, who act out from egregious misunderstandings of capitalism taught to them by college professors who dreamt up their ideology with the aid of hallucinogenics and other mind altering substances in the late 1960s.

It is also an act of increativity, since the culture jammer is freed from having to create something original of their own, and instead barnacles their messaging onto an existing work of art, mass media, or communication.

"Dude, my professor told me that if I spray paint Che Guevara on a McDonald's billboard that I'll be culture jamming Mickey Dee's capitalist signal so they won't be able to disaffect the disproportionate disparities of the disenfranchised with their concentration camp chicken, man."
