You can use this to blame cat people, but this is just a class of people obsessed with buttholes and poo. I'm remembering a post a while back where someone had made a little dog bun, and if you pressed down on it, chocolate came out of it's butthole. Nasty.

Edit: Pic is the first thing I got off google typing in 'dog bun you press that has chocolate come out.' Obviously this wasn't the same thing I was talking about but I refuse to search further.
