There is a word in the english dictionary to specifically describe the act of eating ones poop.
Coprophagia. Yup, that is a fancy way of saying "poop-eating".
Just the other day, I was trying to think of the word, it was on the tip of my tongue, but it wouldn't come to me...but alas, it was coprophagia. Duh.
So Many of the Things!
