Jerome Gambit: What Is This Garbage?

Here is a link to a Jerome Gambit video by International Master Eric Rosen titled "Jerome Gambit Gone Wrong (kind of)". 

About a year and a half ago ("Jerome Gambit: Recent Videos") I posted the link, but without the title of the video, just the url.

And if you search this blog for other examples of the word "garbage" you are likely to run into the post "Jerome Gambit: First There Is The Confusion Factor" which has this sage reflection

I am reading IM Sam Collins' Gambit Busters (Everyman Chess, 2010) with a know-your-enemy focus, and enjoyed the following, from the chapter "Escaping the Defensive Mindset"

It is well known that club players, typically, go to pieces when confronted by a gambit. Of course, for every player there are some gambit lines which they know, and perhaps their theoretical knowledge will suffice to get them to a safe position. But this won't be the case when they are confronted by an established gambit they don't know, an unusual or forgotten gambit, or where their opponent deviates from theory.
