Initially created to avoid having to say the term "groomer" (or relative terms such as "grooming") aloud when in the company of people, or in a place where you'd rather not have people hear you talking of such a topic. Especially when it comes to discussing the topic to someone who is easily triggered by the initial subject.
"Door-to-Door Calendar Salesman" is a code-term to use in place of a "child groomer."

"Selling calendars" means to commit the act of grooming.
"Going door to door" means they're searching for minors to groom.
"Asking a minor for calendars or photos of their calendars" means they're asking a minor for illegal sexual favours, or for sexually explicit photos of said minor.

Person A: "Have you heard that Onision has been going door to door and selling calendars?"
Person B: "What the fuck is up with that? Selling calendars...He should go to prison for it."
