It looks like it's supposed to be a healed severe-burn victim, or someone who lost his skin, ears, lips, eyelids and most of the flesh from his face and jaw in some horiffic motorcycle crash 30 years ago... being forced to kiss some unwilling girl who is being saturated with milk, by two overweight slobs... in someone's bathroom.
Oh, and the burn victim/motorcycle mutilation guy looks like he's got full body deformeties, too. Perhaps he is supposed to be someone from a mental institution, or at least someone with mental issues... given the grotesquely unkept nature of his nether regions and the fact that it almost looks like he's being held back as opposed to forced into the situation like the girl obviously is.
Or
Perhaps it is just supposed to be a human muppett.
Either way... it makes me sick. A neat image.
