The irrational fear of acronyms. One might have been in a very confusing conversation, not knowing what they were being told because of the excessive use of acronyms. When they hear an acronym, or see one, they have similar panic attacks and feelings to that of other phobias.
Dude, I've got Acronyphobia. I can't bear to hear or see an acronym, and just talking about it makes me shudder.
