dogpiss means your bad or dogshit at something but worse than dogshit

Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.

Essentially it’s the polar opposite to phrases that use the word “Piss” to imply something is easy such as “Piece of piss”, so Dog Piss would be used to say that something is hard or difficult. It’s related to the phrase “Dog Shit” in the sense of conveying negativity.
