For women who have recently given birth to a baby, and they are out of the house but forgot to bring their breast milk pump with them so they can alleviate the pressure build of milk in their breasts.

They can find a public restroom, alley way, garbage can, or any other discrete spot to squirt some out into the street. Instead of Breast Pump, it's a Street Pump
My friend just had a baby and wanted to go out to have some drinks when she started to complain about pressure in her breasts due to the milk building up. All of a sudden she whipped her boob out and started to Street Pump the milk right into a garbage can! It was awkwardly sexy.
