MLP pornography
MLP is My Little Pony? How does this manage to make it into the list? Horses mating is neither particularly erotic nor particularly disturbing. Or if it is MLP/human pornography then the rather artificial and colorful look of the ponies would give an aura of "sex toy" --> so not anywhere near 2girls1cup callibre.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
