Shitstaining

When you purposely ride your bicycle through mud puddles and it creates a mud streak from your ass up your back.

I shitstaining on the C&O canal bike towpath after a heavy rain. I can feel the water cool my butt crack.

Schrödingers Shitstain

The puzzling ruination of a public toilet by a shitter before you. As the offender could have been ANYone before the discoverer, hence, Schrödingers Shitstain.

"Don't use that fourth stall, bro -- Schrödingers Shitstain alert! And no, in the immortal words of Shaggy -- it wasn't me"

"If I find a Schrödingers Shitstain again after the barbeque this weekend, I'm gonna lose it."
