Grumble Porn

The most disgusting porn in the world - combing all elements of repulsion to create something which will make most sane people vomit, includes:
Coprophilia, bestiality, cum shots, sadomasochism, necrophilia, midgets, old people and zankos (see definition of a zanko)

really sick hybrid porn, especially that porn which involves not only dwarves, but shemale scatophile dwarves

a combination of the sickest, most disgusting porn

an example of grumble porn is:
a still born male siamese horse with it's head up with mother's arse being shat on, with a male old midget bum fucking it whilst spank the horse with a whip

You see your parents / grand parents / great grandparents fucking
