Is this a common thing? Never heard of it. Also seems ultra specific, like only eating the north side of rice kernals when at a thai restaraunt in taiwan with a Vietnamese server that only accepts line pay in Yen.
edit - no, not for the ligma. I was teaching in NY for the year before we came here, and the 7th grade lads were at least creative enough to slide it into an earth science discussion on minerals. “Mr Leggat, can you tell us about Ligmeus rocks? What about sugmeus rocks?” To which I replied “Certainly, Ligmeus/Sugmeus rocks are what we call polymorphs, meaning they have the same chemistry, but different structure. They are both in the Detentionite family of minerals. Would you like to know more?”
Paraphrased to make myself sound cool, but that was the gist of the exchange.
