Packie, pronounced the same as **** is another one of the million nicknames the yanks have for Patrick. It was a bit of shock to hear first time.
As for the Chinky thing, I have to admit it’s a word we use in our house to refer to the food / takeaway, not the people. Hadn’t considered it even rude up to now. I heard people in our local say aloud on their mobile “do you want anything from the Chinky?” No eye brows were raised on either side of the counter.
A lot of this comes down to how and why it’s said an in what context. **** as a shortening for Pakistani was taken and made a slur by the far right and the hard of thinking years ago, it’s sad really, I’ve no desire to use it anymore, but on the face of it, it seems a perfectly harmless shortening like Scott for Scottish, it’s arseholes using it as an insult and stealing word and making them nasty. I used that word in everyday use as a child without a hint of malice or hate, but now I wonder if I was upsetting people unknowingly.
