~~**Edit** It seems another user posted [essentially the same question](https://math.meta.stackexchange.com/questions/33752/user-changing-terminology) here while I was writing this one. I'll close this question as a duplicate if/when it becomes possible.~~

I got a notice earlier this evening that another user had edited a [7-year-old answer of mine](https://math.stackexchange.com/a/1074697/155629), replacing the term [*Hawaiian earring*](https://en.wikipedia.org/wiki/Hawaiian_earring) with the term *infinite earring*; looking at the editor's recent action history shows that they [replaced the term "Hawaiian earring" in a large number of questions and answers yesterday](https://math.stackexchange.com/users/274352/santana-afton?tab=activity&sort=all), including the question to which my answer was submitted. (Incidentally, the editor has performed only two other actions, both of them minor, during this calendar year.) I was unfamiliar with the latter name, and that unfamiliarity is consistent with the relative frequencies of usage here: Searching for `"Hawaiian earring"` returns 132 results whereas `"infinite earring"` returns only 21---and nearly all of the occurrences of the latter were added by the user yesterday.

I'm unaware of any discussions re the term here in MSE Meta, so it appears this blanket change was unilateral, and since it makes existing posts less searchable, it apparently reduces the site's usability. I've since reverted the change to my answer (but not the change to the parent question), as in my view the (much) less familiar term makes the answer less helpful.

There's a potentially delicateness about this particular change: Glancing at the [Wikipedia talk page](https://en.wikipedia.org/wiki/Talk:Hawaiian_earring#Requested_move_20_June_2021) for the Hawaiian earring article shows extensive discussion about renaming the article in the same way, with some users arguing that the epithet *Hawaiian* is culturally (in)sensitive, in which case I'm sympathetic to the change and will re-edit my answer accordingly, but the applicable claims posted on the talk page are unsourced. In particular one user writes the following---

> 
> The use of "Hawaiian" in Hawaiian earring originated in the 1950's to identify this space as being "exotic." It has no apparent connection to Hawaiian mathematicians. This particular use of "Hawaiian earring" perpetuations [sic] the association of Hawaii and Hawaiian native culture with that which is exotic."

---but I wasn't able to find anything to substantiate that claim, or that gives any etymology for the term at all, in a quick Google search.
