The definition of GDI is not completely known by greeks mainly because they havent seen them in about three and a half years. Nobody knows what they could possibly be doing with their lives because the greeks are too busy being fucking awesome and living their fucking awesome lives. Greeks dont even notice people who dont wear letters. Gdi's are invisible for all intents and purposes and are not worth the time of day. Good luck in life gdi's...sorry your not in the elite group of humans.
Some people pretend to have fun in college (gdi's) and others actually do(greeks).
