It was a metaphor. Get your shit together, Tyrone.

It is suggested that our eating rituals are sadistic, as though they're something torn out of fiction. The character in the picture finds our approval of something so surreal to be peculiar, and the metaphor is used to illustrate this. The character is essentially saying "this is like mythology", implying there's something other-worldly about the brutality involved.

TL;DR I am a huge faggot please rape my face.

What you haven't considered is that he actually says that in the movie

yes i've seen it, and it still sounds silly

are you familiar with the term "metaphor"

yeeees, but i dont see how stuffing a pig into itself is any for of mythological metaphor

Idunno, i think he's saying "It's so unlikely that it's almost Mythological" or something like that
