The problem with the golden rule is that different people want to be treated differently, so they may treat you how they want to be treated but not how you want to be treated, and vice versa.
Maybe when you’re struggling with an issue, you want to be left alone to figure it out by yourself, but your friend in the same scenario would want someone to start doing anything to help out and insisting on troubleshooting the issue together. So your friend ends up frustrating you by offering to help too much when you just want to be left alone and then when they’re struggling, they get upset that you leave them alone to deal with it.
So communication is important. Ask people how they’d like to be treated rather than just assuming they’d want to be treated the way you want to be treated and be honest with them about how you’d like to be treated.
I feel like malaphor should just be a more generalized term for all scenarios since they all involve modifying idioms, whether by combing two or twisting one, whether intentionally or unintentionally since mal- generally means bad or abnormal. Otherwise, a malaphor should probably be considered a sub form of whatever term you find for both.
I’m not finding any prefixes that seem better than trans, though I feel like there’s one that is escaping me that means something like “twisted.”
Possible options: meta, trans, per, dys, dis, para, caco, terato, skew, aniso, morph, neo
