What's the deal with "limerence"?
I feel like I see this word at least once a day on Metafilter, and I've literally never encountered it anywhere else. I just polled a couple of highly educated non-mefite friends and they had never heard it before. I'm not complaining really, just curious how a lexical meme like this gets started on Metafilter.
I think I remember seeing an FPP about it that introduced me to the word and may have been the beginning of its ubiquity here, but the only one I can find is this
which feels too recent. Was there something earlier? Was there an off-Mefi article or book that popularized the word? And are there other examples of an unusual word that's become similarly popular here, to the point where we assume other mefites know it when we wouldn't make that assumption in different company?
