Hi everybody, my girlfriend showed me a Tiktok about manga authors adding unnecessary incest plotlines to their works and I thought immediately "They are from Monterrey" (we are from Mexico).
I remembered that the States have a similar joke about Alabama and I started wondering if other countries also have a state or city associated with people who are, for some unknown reason, attrated to their cousins.
Here in Mexico there even is a kind of saying for these people «A la prima se le arrima».
Also, historically that's way more of an Appalachian (and especially West Virginian) thing. Isolated mountain passes meant that for some families, they were the only people for miles. The Deep South is mostly flat plains and swamplands, thus they had less incest.
