It is commonly used in Scotland, however, it is offensive!
Is it commonly thought an affectionate term?
Not in my experience.
When I was young it was never used affectionately, just a commonly used term for a Chinese takeaway.
However, over the years, people have realised that it is not an acceptable term.
Whenever we taught anti racism programmes, we stressed that these terms were no longer acceptable. However, as the parents and grandparents used it at home, it was very difficult to change that mindset.
