I went way back, and there are zero references. It was just the time of the year, like JOEBIDENISCREEPY pointed out.

October is #NationalPizzaMonth the furthest back pic related to pizza is 8 weeks ago. October 1st, the last pizza image is 4 weeks ago, approx October 31. The spooky satan cultist things are all arount the 4-5 weeks ago timeframe. which is Halloween.... This is all just observations from touring around the pabst instagram page... I could be wrong, however I try to think critically and feel that the pizza pics and devil shit is merely seasonal.
