The act of discovering that during intercourse with a woman, your penis has been shit upon, and that said girl is also on her period; as well the discovering is marked by examination directly after your climax during vaginal sex.
Thus creating an instance of bloody shit covered cum dick, much like that of a neapolitan ice cream bar.
