For those of you not in the know, this is a reference to the hero protagonist of the book Snow Crash. His job, at the start of the book, was as a delivery driver for a pizza franchise ran by the mob. His name was Hiro Protagonist. The book is quite good, I recommend it highly for a fun retro futurism. It pretty much invented the concept of the metaverse. The audio book is my preferred way to "read" it.
