agitprop: noun and adjective (Popularity: Bottom 50% of words [[agreed]]): Propaganda; especially: political propaganda promulgated chiefly in literature, drama, or art.
Etymology: Agitprop is a curious sort of portmanteau, blending parts of two words, each from a different language. It comes from the Russian word agitatsiya (“agitation”) and the English propaganda (“the spreading of ideas, information, or rumor for the purpose of helping or injuring an institution, a cause, or a person”). An agitprop agent is called an agitpropist.
