I coined the term - and it turns out someone else did too, for something else. So be it. If someone else can think of a better term that's never been used before, then I'll happily use that instead.
The earlier usage mentioned in Wikipedia is entirely uncited there however, and seems to have only been used in one academic project AFAICT.
"In some cases the estimates may be obvious. Perhaps the story is similar to others that have already been completed. In other cases the story may be very difficult to estimate and may require exploratory programming."
I agree - it's what made me raise an eyebrow... However, based on their comment above, the lead author of Nbdev believes to have coined the term.
My opinion is that due diligence and attribution are important. If I believed I'd coined a new term, I'd check first. Mistakes are easy to make, but when highlighted, perhaps corrections are more appropriate than negotiating with the person highlighting them:

Why are people nitpicking about this? So the term/phrase he came up with was so descriptive that other people had also thought of the same term previously. He didn't steal anyones research on the topic, or steal code for the project, or deny credit to a developer working on a project. It's 2 simple words that are extremely common in the english language. Of course lots of people have happened to put them together before.
This is my second time on hacker news, and I don't think I will be back. Why not offer to help the project, or show support? Why try to find something to fight about? It's just demoralizing to see the lack of kindness from people.
In electronics, we call it Breadboarding, and the results are expected to be temporary by all involved. Breadboarded circuits generally are not stable over time or movement.
