A portmanteau of 'naff' (British slang meaning lacking in style or good taste : vulgar and unfashionable, American: tacky) and affinity, to create a word which is a perfect antonym for affinity in a cultural context.
I have a real naffinity for Florida: I think it's a bit rubbish but it's also kind of cool and hilarious, and I also kind of secretly -not-so-secretly love Disney World.
