A compound word made from the words "balls", "back", and "action". Ballbaction is when one male playfully accepts a piggyback or shoulder ride from someone, and instead of mounting them smoothly and majestically, slams their testicles into the back of the person giving the ride.
He just wanted a piggyback, but ended up giving John ballbaction.
