You chose to opt out of living your own life in order to watch someone else's life. You watch life go by rather than participate in your own life. The Azure Piller's personal life is rather
boring; other
people's lives are more interesting than their own. So, you would rather just be a watcher. Azure Pillers consist of
people who are addicted to reality TV, playthroughs, speedruns, spend all their
time browsing social media, etc. It also includes
people who are hooked to the screens of their smartphones. This is in the same vein as the Red Pill, Blue Pill, Black Pill, etc.
The 1998 movie "The Truman Show," a comedy and sci-fi movie, is a great example of the Azure Pill. Everybody would rather watch or talk about the life of the main character, Truman Burbank, on TV than experience life for themselves.
