Non-greek, non-person that can be spotted rocking WWE teeshirts, gel-crusted hair, cargo shorts, tennis shoes, longboards, and snapbacks. Is an initialism for god damn independent but should never be capitalized because they are not worth holding the shift key for. Can often be heard bashing the greek system after embarrassingly being denied entry into a house party on multiple occasions for which it was not given the address but followed the tracker on its girlfriend's phone. On the rare occasion that a gdi is allowed entry, it will almost certainly die of alcohol poisoning and give the chapter a bad name.
Today a gdi asked me why I'd want to pay for my friends. I told him he couldn't afford to understand. TFM
