I like the term. I have been using a similar phrase "looks good in a snippet" when referring to certain styles of programming.

Once such instance was when nodejs was becoming popular and everyone was showing how easy concurrent programming can be with a few callbacks in a snippet. However building a large code base with that would eventually turn into a nightmare.

Another example is databases which don't fsync after writes by default. They look great in benchmarks (webscale even!) then in production suddenly some of data goes missing. But at least those initial benchmark demos were impressive.
