urban cattle 

almost brainless humans who wander about cities, stepping into traffic, standing on the white center lines as cars zip by. Also move aimlessly on sidewalks, often blocking or forcing those actually going somewhere with a purpose to go around them. Similarly to the cows that reputedly wander the streets of large cities in India more or less as they please.

The traffic lights had a count-down to when the pedestrian crossing would commence, but the urban cattle were already off the curb at minus 10 seconds, targets for any fast traffic running the crosswalk on yellow.

Urban Sand Castle 

When a public toilet becomes clogged, but people continually defecate into it, overfilling it with feces until the fecal matter stands on it's own weight in the bowl and over the toilet itself, often resembling a sand castle.

Man, did you see that sweet urban sand castle in the KFC bathroom?! It's getting huge !
