Sensationalist coverage of "trends" happening among teenagers to scare the shit out of their parents. Although occurences of these "trends" are totally infrequent and not really an actual thing in the adolescent community, parentaganda usually results in higher ratings for these slow-news-day reporters and annoying, awkwardly posed questions from concerned parents to their kids.
Mom: "Sweetheart...are you and your boyfriend/girlfriend sexting?"
You: "No mom, thats just a bunch of parentaganda."

Parents: "Son, we need to talk to you about the dangers of choking yourself while masturbating."
You: "OH GOD, NO! WHY, PARENTAGANDA, WHY?!?"
