An inside joke between Eileen and her fanbase: Eileenism is the "religion" on the worshiping of Queen Eileen. Eileenism has recently grown even bigger with other Instagram users tagging Eileen on pictures that they edited to represent Eileenism. There has even been a group on Kik that Eileen is involved in made with the tag eileenism.
Eileenism was created by a fan stating, "U r a godess #eileenism new religion." Eileen posted the comment on her Instagram @eileenspams and several posts related to the joke have been on all three accounts of hers.
