Can you be more specific about how you want it broadened? Reaction from friends or other relatives, and not just parents?
Speaking words of fandom: let it squee, let it squee.I personally am OK with it staying as it is and there being a new supertrope for Character is about to marry evil person; people try to stop the wedding rather than just Mom's going to marry Evil Bob; stop the wedding.
The name certainly sounds broader than the trope, and there is definitely a broader trope we could have. The two obvious solutions are: broaden the trope (a lumper approach) or trope transplant (a splitter approach, I guess). Since I'm neither lumper nor splitter, I don't have a preference, but I do think it's worth doing something here, and I tend to think this name should go with the broader trope—however we end up creating that broader trope.
The name might also be a little non-indicative even for a broader trope; I'm not sure.
Speaking words of fandom: let it squee, let it squee.Hi. I actually think i already did the broadening, just with a few touch-ups to the description, to simply state that it does not necessarily have to work in the parent-child relationship. Some of the examples in the set were already technically not applicable under the old definition (namely Chef and South Park, since the old terms seemed to strictly define a parent-child relationship)
The major point that i feel could be added that seems to often apply to this plot-type, which was what i was really going after with my YKTTW entry, is the notion of people (whether that is the spouse-to-be or the friends or associates of the protagonists) thinking that the protagonist is just being petty and/or jealous when they air their suspicions, often jeopardizing the protagonist's friendship (like in My Little Pony, when even Celestia began to doubt her prized pupil after she called out Cadence)
The big issue with this one is the ambiguous stock phrase name. It has little to do with the trope.

In YKKTW people noted that this plot is child focused and the trope could be broadened. Since you probably can't just broaden tropes without asking, I came here.
