Biggus Dickus is a fictional Roman nobleman and officer in the Monty Python film Life of Brian.

From left to right: a Roman Centurion (John Cleese), Pontius Pilate (Michael Palin), and Biggus Dickus (Graham Chapman).

He is married, according to his friend Pontius Pilate, to Incontinentia Buttocks. Like his friend, he has a speech impediment - he lisps. This is the cause of public hilarity when he reads down a list of incarcerated wrongdoers, e.g. "theveral theditiouth thcribth from Thaetharea".

We can assume Biggus to be of patrician descent and hold at least the grade of Legate, as, again according to Pilate, he "commands a cwack legion" and "wanks as high as any in Wome" [sic].

Whether "Biggus Dickus" refers to the man's cognomen and/or agnomen or should be taken to mean his nomen and praenomen (i.e. Dickus from the gens Biggus) is debatable. While it would be more appropriate for Pilate, in the formal public settings as depicted in the film, to use his friend's full name, it was common for agnomina, or nicknames, to refer to a physical trait. In any case, the name is obviously meant to be taken completely seriously, as indicated, in the film, by Pilate's treatment of soldiers who commit a career-limiting move by doubting the name's veracity.
