When a somewhat round projectile is thrown directly into your scrotum, causing pain that can only be described as a nutblast. The 'testicle' part comes from both the shape of the object, and to help specify which kind of nut is blasting (as opposed to an edible nut, or nut (meaning to ejaculate))
Man 1; Dude, my girlfriend was so mad when I forgot to let the dog out to wizz, that she gave me the biggest, most horrendous testicle nutblast of my life!!!
Man 2; Ohohoh dude I can feel it! I can only imagine! Rip future kids!!
