2.
The act of giving two handjobs to two separate men at the same time. This term was "dubbed" as jumper cables because "positive" and "negative" penises being black and white, though not necessarily referring to this. Used sometimes to describe brothers on the DL. Real dedication and skill have to be used to create the appropriate amount of pleasure in both parties. Both members being pleasured must ejaculate at the same time, just like jump starting a car.
I gave jumper cables to my dad and brother at the same time, and it really jump started my heart (mouth).
