People have shown up for greek sings and greek week events at my school wearing GDI letter shirts. They were there cheering on the competators, too. I've never refered to myself as a GDI, because I think it is disrespectful (that and I don't like the "GD" part of it.) Anywhere on campus that you see any greek graphiti (elevators, desks, etc) you will also find GDI graphiti. It's usually only used by the people that either got rejected during rush, or had a bad experiance with someone who was greek. I know a lot of people that claim to be a GDI, and once a greek shows them any kindness or attention, they drop the title. I really don't know what to think... *shrugs*
Interesting side note: there is a group of 3 Russian girls at my school I know that made themselves letter shirts with GDPhi on them, standing for God Damn Forigners. I have to admit, it was kinda cute
