gdi
G.D.I.

Stands for God Damn Independent
Deriving from the latin word "gidiom" meaning stupid lame asshole who can't get girls and isn't allowed in any parties.

Definition: A non-impressive, ordinary person with no sense of style or social skills who was not fortunate enough to recieve a bid from a fraternity because they were not good enough. Instead of contributing to the college community, G.D.I.'s drive around in lifted trucks wearing affliction shirts and sweatpant shorts hating their lives and despising themselves for not being a better person and taking part in Greek Life.
"Fraternities are for gay guys man! I want to rage in my dorm and play World of Warcraft with my friends because im a gdi!"

"Dude people that don't live in frat houses still get girls bro! Trust me I get girls every night!"

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
(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.
