The secret seems to be to acquire a good nickname, like Roger of Chester County, England.
If it is a real name—a nickname, presumably—there seem to me to be two possible explanations for its application to Roger. First, that it applies to an actual event—a clumsy attempt at sexual intercourse by an ‘Inexperienced Copulator’ (my name for Roger), revealed to the world by a revengeful former girlfriend. Fourteenth-century revenge porn perhaps? Or it could be a rather elaborate way of describing someone regarded as a “halfwit”—i.e., that is the way that he would think of performing the sexual act.
Of course, whether you want your name to live through the centuries in that way is an open question.
