Informative murder porn 

True crime shows used primarily by middle aged couples to get aroused. This phrase was coined by South Park in the season 17 episode of the same name.

Randy:"What is Minecraft, and how do you tame a horse in it?"
Stan:"You guys don't need to be watching that stuff."
Randy:"Oh come on! You can't block your parents from watching informative murder porn!"
