I hate hun, babe, darl, doll, chick, sweet, etc. Hate them all. I think it's because nobody I know well uses them so when someone does it always implies a kind of closeness that we don't have, which feels weird and disingenuous? Plus it seems weirdly infantilising. But hun seems to be going full circle now, it's almost used mockingly to take the piss out of the hun types, like with 'u ok hun?'
