GDI 

1)A person not cool enough to join a fraternity or sorority, and spends every night of the week writing bull shit on urban dictionary about greeks.

2)The second lowest form of life next to the dung beatle

I was a GDI in college and look at me now. I'm the assistant manager at Mc Donalds, and soon to be manager after he leaves to college.

Only a GDI would wear jorts.
