Dog shit that has been in the snow all winter. Once the snow melts, you are left with soggy dog poo that keeps it's original form, but is extremely unstable and messy.
Oh great, the snow has melted and now I have a yard full of Sog Shit. It's so hard to clean up.
Dude, watch out- Oh too late. You stepped in that Sog Shit. You are going to have to hose down your shoes.
