The Acronym "AOE" that is associated with the Alpha Phi sorority stands for ”Alethia Orno Eteronis.” The literal translation of the phrase is "Truth, Honor, Forever."
The meaning of the acronym is supposed to be kept secret until a pledge is officially initiated into the sorority. They are not supposed to reveal it to outside parties after they learn it. There was a controversy in February of 2012 when the meaning was revealed on Wikipedia and sourced with a book written by a sorority pledge. Sorority members demanded that the reference be taken out. Wikipedia declined to do so, stating that it was not bound by any fraternity's rules or policies and the information was of interest to the general public.
