The kukui (kuh-koo-wee) nut is from a flowering tree in Hawaii. Busting a kukui is just another way to say busting a nut.
My balls were blue and I was certain I had to bust a kukui on this girls tits. After i did she swabbed it up with a biscuit which she ate greedily, as I informed her that I wouldn't require her services or presence the rest of the night.
