The result of using a "splashgaurd" or "shit raft".
Feces sinks downward, wrapping itself in a comfortable nest of toilet paper.
Highly fibrous or buoyant shits will remain partially exposed to the air in the center of the nest, allowing them to pollute the surrounding air quality, and penetrate the nostrils of others in the area.
Use the other stall, someone left a shit nest in there.
The placement of several sections of toilet paper on and around a public toilet seat, layer upon layer, before sitting down to take a dump or piss, in a paranoid attempt to avoid non-existent toilet seat germs.
I went to go use the washroom at the office the other day and some asshole left his shit nest still assembled on the toilet seat. What the fuck am I supposed to do with his shit nest?
