The mixture of excrement and mud on the floor of a Johnny-On-The-Spot, especially found at rainy festivals.
1. I went to the bathroom and sat my purse right in a patch of moop.
2. Under the tent at the festival, there was a stench that made us all wonder if what we were walking in was not mud, but actually moop.
