A relatively small stagnant body of water, usually curbside or near a storm drain, which contains an assortment of garbage and other waste. They are peculiar because they exist despite long periods of little to no rainfall. The word "bum" is attached because these puddles usually have an oily sheen and can contain articles of clothing, used needles, and broken glass.
After hours of dancing and drinking, the two girls decided to make the walk to the car barefoot. Oblivious to their surroundings, they stepped off the curb directly into a bum puddle.
