It's in many languages even the Quran told us not to say uff to our parentsIt's kind of hard to explain, the closest would probably be the irritated English 'ergh!'. Like imagine a child pestering a parent, the parent starts their sentence of with that^, and then the discipline comes. Sometimes it's used positively though, but most the time it's a negative word and the 'f' is held for quite some time, uffffay.
