In my day job, I work with a search engine, and we're constantly measuring how good our searches are with a metric called Normalized Discounted Cumulative Gain, although nobody ever says that. They just say "NDCG Scores" all the time and people are expected to know what it means.
But even people who know what it means don't really know how to calculate it.

Please give me alternative acronyms for NDCG that I can laugh about everytime I hear someone say it.
