GDI
Someone who doesn't join a fraternity for some reason. Maybe they're a douchebag who shouldn't join in the first place, or maybe they're balled for some reason. Regardless, they are not fraternity material.
"I don't wanna join a frat because they are gay," said one GDI. "Well, I guess you wouldn't fit in to my fraternity anyway. We don't refer to our brotherhood as a frat. Would you refer to your country as a cunt? If you would, get the fuck out of my house. If I see you again, I'll haze your ass so quick I won't even be able to 'ball your ass."

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.

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."

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
(God Damn Independent). A college student who is not an active or a pledge to a particular sorority or fraternity. The GDI has either chosen to not affiliate with the greeks or maybe rushed and did not pledge. GDI's tend to have a reputation of being dorm rats but some GDIs are cool and have some greek friends. Just depends on the particular GDI. Being titled a GDI should not judge who someone is, its just a decision.
What sorority are you?
Oh im not, im a GDI.

gdi
"God Damn Independent"; A college student with the right mind to retain their dignity, individuality, and money by turning away the offers of the Greek system.
Yeah, I was pledging a frat, and I quit after being told constantly that I was "not an individual anymore". Plus, it was more work on top of my schoolwork. What a waste of time. Going back to being a GDI was the best decision I ever made.
