For a male: high GDI occurs when fully incapacitated after morning sex.
For a female: uncontrolled squirting or jello like legs with the inability to stand. Or the mixture of all the above.
What's your GDI at?
Fabulous at being apparently unable to handle ambiguity or individuality of any variety, the term GDI is a universal label applied to all college students who choose not to participate in the Greek system.
Whether the apparent obsession with labeling everything belies rampant intellectual laziness, extreme insecurity expressed in a fear of what is "different" from a certain perspective, or both is an open question.
Either way, the same mentality extends beyond the categorization of the college social structure to brand names (are you a Chanel girl? an Abercrombie man? an Alpha-Delta-Zeta or a Kappa-Gamma-Blamma?), and beyond that to even more insidious forms of labeling, such as racism.
However, it all likely comes down to extreme insecurity being expressed in one particular way; label everything, achieve nothing, derive self-esteem instead from trying to look down upon anyone whom you define as an A instead of an B.
I mean, what Sorority are you in?
None, I'm a human, an individual one even
No you're a GDI
Well, actually I'm here for the keg.
