The ATO fraternity is one in which the men take turns licking each others rectums and then proceed to roofie every girl they come across so they dont have to fuck each other any longer. As part of their initiation, the pledges engage in a contest known as "Smoodgie Cookie". This is when the pledges stand around a cookie and the last one to ejaculate on to the cookie must eat it along with his pledge brothers sperm.
Cant spell faggot without ATO.

Girl 1: Did you go over to ATO's last night?

Girl 1: That happened to me last weekend!!
