1. God did it!
2. God damn it!

GDI 

God Damn Independent; A college student that chooses not to join greek life or a sports team because they have low self esteem but would like others to think they’re confident in themselves. They rarely go to parties due to their lack of knowing people. Basically the worst type of person on this planet.

1. He can’t afford to pay fraternity dues so he’s a GDI scum.

2. She’s pretty hot for a GDI. I would.
