My vomit doesn't contain any digestive juices, it's just food and saliva. Which is edible. Not that the dog ate it or anything, it's just when you spend as much time getting intimate with your toilet face-first as I have, these things actually go through your mind.
Then I had this carryover to a horror movie scene where a mother feeds her "baby" by vomiting into its open mouth, like a bird.
Genius. Pure genius.
