Scrolled all the way down until I found this example, you saved me a top-level comment.

Similarly, in yeshiva communities in the US men and women typically pronounce certain Hebrew vowels differently. I'm not sure what the historical context here is, but this always fascinated me. In any case, women and men speak in noticeably different ways about religious concepts, to the point where adopting the opposite gender's pronunciation stands out as "weird".

In addition to pronunciation differences, using more Aramaic and certain Yiddish phrases is male-coded in this community.
