Dangerous gay sex act where you kick your partner in the balls while throat fucking, simulating a bucking bronco. Sometimes performed with the aid of a tether attached to the ballsack of the bottom, and sometimes performed with the ballsack of the top fully inside the partners mouth alongside the penis before kicking.
Ennis kicked Jack so hard in the ballsack performing a good cowboy mouth that he accidentally bit through and ruptured some of Ennis' seminiferous tubules. It required medical attention, but they both realized their kind of love was never going to need virile, potent, life giving spermatozoa that normal love requires. They both wept in each others arms, tenderly.
