This question was asked on ell.SE - https://ell.stackexchange.com/questions/228380/when-you-frankenstein-a-team-together-is-frankenstein-a-new-verb

...and as answered over there, the verb "To Frankenstein" is a reference to popular culture that implies to cobble together (a team in this case) from various (likely unrelated) sources just to get something working, as the fictional Frankenstein himself did to build a functioning human body from parts of multiple cadavers.

But my question is, what kind of word is "Frankenstein" when used like this? I know it's a verb, but that's not what I mean, I'm more talking about inventing a use for a word whose meaning can be inferred from having knowledge of the reference.

e.g. Is it a metaphor?
