The word of the day is "nicodemously"

I learned it this morning from Zimbabwean author Pettina Gappah when she was interviewed on NPR's Morning Edition. She was explaining "Zimglish" (backup word of the day):

I'll give you one example: Because we love our Bible — we consider ourselves a very strong Christian country — so we have a lot of phrases that we take from the Bible that we think are English words. So for example Nicodemus, is a man, a Pharisee who went to Jesus at night and said, "How can a man be born again?" So to do something "nicodemously" is to do something secretly, under cover of the darkness. So you have politicians condemning the "Nicodemus machinations of the government" and you think ... What? It's my absolutely favorite Zimglish word of all time.
