MOOKs - agrophobic

Massive Open Online Courses (MOOCs) are all the rage now. By chance I found this old t-shirt from about 5 years ago. I had forgotten it bore this legend. I'm not sure what MOOKs were in this context, but I like the idea of being agrophobic - by which I guess they mean against aggression. Or maybe not. Anyway, this t-shirt proves that I invented MOOCs.
