If you understand it correctly, then use correct terms to describe it. And I don't mean the mathematically correct pristine words that some particular FP language uses, I mean, terms that will create correct impressions in the audience and not incorrect ones. You don't help by using the most commonly misunderstood terms and reinforcing the widespread misconceptions about how it works. Both "flatmap" and "chaining" create completely wrong impressions. You just leave people having to clear out the misunderstandings to get to the real and not really that complicated truth.
