(genitals and sex acts discussed in street language, so not for kids or the sexually modest)
From the Monty Python fandom wiki:
Biggus Dickus is a fictional character in the Monty Python film Life of Brian, portrayed by Graham Chapman. He is a Roman nobleman and officer. He is married, according to his friend Pontius Pilate, to Incontinentia Buttocks.
BD’s sexual-onomastic legions have advanced throughout modern media, where they have a particularly powerful role in gay male pornography; some productions are staffed almost entirely by raunchily named performers, their names travesties on those of masculine icons; louche plays on vivid everyday words; and vocabulary smeared with the X, XX, and XXX of obscenity.
Two striking examples that have come by me recently: a man who does business as Feral Fux or Feral Fuxxx; and another who performs as Fabio Stallion or Stallion Fabio.
