How to counter the notorious Blackmar-Diemer Gambit?

My classmate sometimes plays the infamous BDG (1. d4 d5 2.e4) and it is very annoying. I end up losing 3 games in a row by taking the BDG, although declining it makes my pieces passive. Can someone teach me how to counter the BDG properly?

Thanks!

Playing black, I would counterattack BDG with an indian opening: 1. d4 g6. That would make white effort to control center harder!
