I could have sworn I saw this trope somewhere on this site before.
Maybe the trope was unpopular, or maybe it just has a weird name and thus is hard to find, but man, the familiarity vibes are overpowering!
Either way, carry on with this discussion. If we have this one already, and the original trope is one day unearthed, Wiki Magic will take care of it...
I can always ask on the Trope Finder page — those guys are good at pointing people to that one trope that was something like that other trope but totally different.
