When I say "high school movies," I basically mean '80s high school movies. I honestly don't think you can make a Ferris Bueller or a Sixteen Candles today "unironically" -- or what have you. (Ironic is in, on the other hand -- see Superbad, Napoleon Dynamite, 21 Jump Street, Clueless.) High school as a setting isn't going away ever, though I wish we all could at least take a sabbatical in order to come up with some original plots. Transformers was sort of set in high school, at least the first one was. And so on. But high school as a memetic (keep in mind I originally mentioned the high school trope, not the high school movie; different animals -- realistically I know it won't vanish but I don't think we'll ever see the Porky's style again per se.
