Somewhat recently I showed how acronyms scarcely existed prior to the 18th or 19th centuries, and that their rise is tied to a shift toward a more autistic or Aspbergery mindset. The examples were from hard and well as soft science. Still, finding them in geeky areas of academia isn't too surprising. But what about where you'd least expect them? That shows just how autistic people become as they genetically and culturally adapt to modern life.
Within English and folklore studies, there's the viral acronym FOAF -- "friend of a friend" tale, meaning who the supposed source of some urban legend is. These people are arts and humanities types, not the ones who are supposed to be dorks.
Then there are the even fluffier fields like queer studies, women's studies, etc. There and within related activist groups, there's some permutation of the widely used acronym LGBTQ (that was the form I remember among the "theory" people and activists at Brown), standing for Lesbian, Gay, Bisexual, Transgender(ed?), Queer. "Gay and lesbian" or "homosexual" or whatever just won't do -- an acronym must be coined!
Weird sexual preferences even among straight guys are also littered with acronyms, which you can look up on your own: BDSM, CBT, CFNM, and the most mellifluous YKIOK,IJNMK. Not being a porn hound, each time I tune in there are at least one or two new genres with cryptic acronyms as names since that last time. You can bet that these genres have a nerdier-than-average fan base. This isn't an academic field at all -- just porn. Earlier I mentioned the alphabet soup of terms found among PUAs.
Video games also show lots of acronyms, even though they aren't inherently geeky -- they're just toys or games. But the ones that appeal most to the Aspbergery mind are full of them -- RPG, MMORPG, LARP (not a video game, but related), and terms like MP, HP, XP, NPC, etc., not to mention the names of their favorite games. Hardly anyone refers to SMB (although that term does exist; just not popular) for the Super Mario Bros. games, or DD for games in the Double Dragon series, and so on. Yet just about every role-playing game is referred to by fans in acronym form: FF, BoF, CT, SoM, etc. And while role-playing game terms are only referred to by acronyms (XP, NPC, etc.), no one does this for platforming games like Mario Bros. -- "one-hit death" is not called 1HD or OHD, "mini-bosses" are not called MBs, and so on.
Every group wants to make shibboleths to distinguish in-group from out-group members. But in a pre-modern world, people were creative enough to coin whole new words ("transubstantiation") or evocative phrases ("Sturm und Drang"). With the shift toward autism and lower creativity, no effort is made to endow today's jargon with any charm -- just begin with the most straightforward and anodyne description of something, then turn it into an acronym (like "U.F.O." or "IS/LM"). And as the above examples show, it's not just the inherently geeky areas of life that are being colonized by acronyms -- games played for fun, sexuality, and the arts and humanities are also under attack. This has less to do with the essential qualities of the domain in question and more to do with the people whose desires are reflected therein.
