When I was young (1980s), and violent or sexual programming was advertised on television with the disclaimer, "Parental Discretion Advised," I thought the TV announcer was actually saying "Friendly Discussion Advised."
It made sense to me because I thought the extreme nature of these programs would make people feel scared and leave them with a need to reassure each other.
