When a male whacks a sexual partners butt after intense sexual intercourse. He then proceeds to swing his cock in circles causing him to fly, this allows him to smack the sexual partners butt more causing them to fart. The fart contains toxins that make both partners obtain rabies, their mouths start to foam and from there, they run around and bite people. This causes the whole process to repeat. The next day the toxins wear off and their mouths stop foaming.
