street gravy 

Street Gravy is the standing greyish, oily, and slightly thick water that collects in city streets. It's perpetually there, even in the summer..somehow.

It's primary characteristics are that it's gross, it's of unknown origin, and it isn't any clearly distinct origin or composition. e.g., it isn't motor oil, fresh water, etc. It's some amalgamation of city filth in liquid form.

Ugh. I stepped in street gravy on Houston. Time to cut off my foot.

Street Gravy 

Puddle of unknown, mysterious liquid. Usually in a city.

I was walking down Main Street when I stepped in a puddle of street gravy
