Of Jamaican-Canadian origin.
While having sex with a woman, usually one that is quite large or overwieght, the male not only slips his penis into her vagina, he also stuffs his testicles inside of her. This is continued, with a slightly shortened pumping motion untill ejaculation. Also refered to as, "Balls-n-All".
I met this mass-gyal at the club and mashed that ass steady. When I got it ripe and ready, I stuffed in my nutts and was juxing her ting until I got that nut. Big up yourself!
