Abstract: A method of spraying a posterior portion of a human person includes disposing an aerosol container in an aerosol container receiving bay of a strap-based aerosol delivery assembly. The aerosol container has product therein and a dispensing button. The aerosol delivery assembly includes: the aerosol container receiving bay having a fixed length perimeter; left and right grip sections disposed on opposing lateral sides of the aerosol container receiving bay. The method includes disposing the aerosol delivery assembly such that the aerosol container receiving bay is disposed posteriorly relative to the person, and while so positioned, dispensing product from the aerosol container toward the person's posterior by pulling the left and right grip sections away from each other, so that a vertical height of the aerosol container receiving bay is decreased to thereby depress the dispensing button of the aerosol container. Related assemblies are also disclosed.
