When you fist your entire hand into a lady's anus, effectively making it unusable, and then using the same hand to finger her until she cums, and when she does, dump it in her asshole, and wait for her to take a shit, when she takes a shit, you take a shit in her asshole at the same time, when you are both finished, proceed to scoop up the entire mess into a jar, then release liquid nitrogen on the jar, have the entire thing freeze then break the jar, when the jar is broken, you shall feed the shattered jar to your pet and wait until it dies, once it is done, take the dog to your local chinese restaurant and force them (preferably by blackmail) to cook it, you then bring the cooked animal home, then combine it with the shitty cum thing from earlier, you then blend it, and give it as a smoothie to some niggers down the road, once they eat it and die, take their bodies home and eat all them niggers, remember those chinese chingtards from earlier? take them with you to watch you do the whole thing again in a few hours.
