A pile of dog crap found in one's yard or a public place that was deposited at least a week before it was discovered, and is currently in a state of decay. It can sometimes resemble mud or a stone, and may cause momentary confusion when encountered.
While walking through the backyard, Maria stopped short to avoid stepping on a mysterious object. Upon closer examination, she realized that it was a pile of dog crap she had missed on an earlier poop patrol, and the pile had since become a decrepiturd.
