GDI 

An insult used by pretentious idiots in Greek organizations to try and make those outside of their membership seem "beneath" them. Pretty much as childish as it gets.

The frat boy called the non-Greek student a "GDI". The non-Greek student proceeded to laugh at the immaturity of the frat boy.

GDI 

God-Damn Independent: term used by college students to refer to a non-Greek student. In a derogatory sense, it is used to refer only to those who choose to bash the Greek system. Contrary to popular belief, it is possible for Greeks and GDIs to be friends.

Despite the party's location on Greek Row, many of the people who showed up were GDIs.

GDI 

Acronym for "God Damn Independent," often used in a derogatory way to refer to a college student who chooses not to join any sorority or fraternity.

Seems to be used in a derogatory way the most by people affiliated with the 'Greek' system because they do not realize that 'independent' really isn't even an insult. Typical brainless, follow-the-crowd, frat people. Damn, frats and sororities are like cults. People go in fine and come out brainwashed, dumb, and/or slutty. IF they ever come out.

Vic: What's your title?

Sam: What?

Vic: You know, what frat are you in?

Sam: Oh, I'm a GDI.

Vic: Wow, I really think you should go Greek.

Sam: You know, they're not even really Greek. They just jacked the Greek letters and twisted them to use in their half-assed, drunk-partying organizations. I only rushed for the free food. You'd have to pay me to join one.

Vic: Why don't you join?

Sam: Um, it costs money I can't afford to waste, I can make friends on my own time, I don't really want to be saddled with people I don't like, I don't like to do pointless shit, and I don't like how they always call each other 'big' and 'little.' It's hella annoying. Oh, and I don't really like to conform.

Vic: What's 'conform?'

Sam: *sigh*

gdi 

1. "God Damn Independent" - A derogatory term used by members of Greek organizations to describe someone who has sufficient intelligence and social skills to simply make friends, not pay for them.

"Look at that GDI, he'll go somewhere in life, unlike the legions of coked out worthless douchebags who were misled into thinking that joining a fucking frat was a smart decision."

I just took the time to rip on the greek system on urban dictionary because I'm a GDI.
