Someone not cool enough to be in a fraternity or sorority and thus has to talk shit about the Greek system. If only you were cooler you weak motherfucker. Fuck you.
Nathaniel rushed SigEp but was not of adequate quality to get in. Poor guy, he will always be a GDI.

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.

God Damn Independent. Has No affiliation in the Greek world. Many GDI'd are looked down upon. If someone in a Fraternity or Sorority would happen to see a GDI you would most likely feel compelled to Kick there ass.

At my college, a person who calls them self a GDI is a hypocrite. They look down on anyone in a fraternity and pretend they are against the idea of fraternities. But in the same breath, they brand together and call themselves GDIs, they have a GDI house that holds parties, they wear clothing that says "GDI", and they have GDI formals. They dress in bright neon clothing, skinny jeans, and flat brimmed hats. They bash fraternities and believe they are smarter and cooler than any Greek.
It's funny because GDI hates frats with such passion, and yet they are oblivious to the fact they act just like a fraternity.

"Frat parties are so lame. Come party at GDI instead, where we'll do the exact same thing frat guys do, but at half the fun."
