Cloud of Brown

When a turd is flushed, but does not go down and ends up sitting in the toilet water. When it sits for many hours degrading, when the toilet flushes a again and disrupts the environment and creates a "cloud of brown" in the toilet water.

Oh boy, I just found the deuce you dropped a few hours ago still bobbing in the toilet! Oh boy did I shake up a cloud of brown in the toilet water when I flushed it down. Here's a saying. "When you happen upon a turn in the toilet bowl, flush it down, just be prepared to create a cloud of brown"
