The shit that is left on the ground or sidewalk after picking up after your dog.
Guy 1- Man you've got some serious dog rash there.
Guy 2- Tell me about it. Mitzi, my four legged friend, ate something that didn't agree with her and now it's squirting out her ass. Hey do you have a paper towel? This shit is seeping through my fingers.
Guy 1- That's sick man. Just spread it out really thin across the sidewalk. Hard or soft that's what I do.
Guy 2- What?
Guy 1- Yeah, it drys a lot quicker spread out and then I don't have to carry a bag around all the time.
Guy 2- Gross! You should pick up your dog's shit.
Guy 1- What!? Look at all the dog rash around here! Obviously I'm not the only one.
