Frat boy Brock aspired to in a fraternity after his father, he got mad pussy in high school but was skinny when he went to collage he put on his freshman 20 and looked like a fucking Calvin clien model. Because of this he now gets more puss. When he gets out of his collage trance he will become very successful unexpectedly he will become rich and because of this he will get even more puss, possibly even quadruple the amount of collage. Frat boy Brock is a fucking legend.

The kind of faux realism applied to fantastical material so that average viewer will believe it; the point at which the idea of realism simply translates to compromising fantasy in typically fantastical material, adding lots of black, blood, sex, or making it "dark," because that means it's serious grown up business; realism that results in drunk, college idiots proclaiming "that's so badass!" and marveling how deep they must be to "get" the goings on.
A great example of frat boy realism: "So the new Spider-man will be gritty and dark this time and not fruity and lame like the other ones?"

I'm starting to feel like one day I'll be feeling something similar about Christopher Nolan's "Batman" movies... loving them as films but HATING the impact they're having on genre film, i.e. making this kind of frat boy realism the order of the day.
