Someone who has no merit, no social status. One of the lowest in the ranks, a grunt who has to shag balls so as not to be seen as completely worthless.
The act of taking a baseball bat and hitting someone about the knees, shins, ribs, head, or any other part of their body, in order to extract some cold-blooded retribution. Usually practiced by the mafia (or angry dads who just found out their daughters got boned by a dude they disapprove of) or anyone who wants to make a quick statement loud and clear.
Did you hear those c***suckers got what was coming to them? Vinnie just got back from ballbatting their knees after they ducked him for more than a year for the 5 grand they owed him!
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.
