There are much kinder ways to communicate; I am a Dr. Benjamin Spock graduate who learned, early on, that a parent needs to treat the children with as much respect as house guests. Presuming we are gracious to our guests.
At this point, someone else chimed in, "I think 'shut up' are the worst of words, and then another nominated "you dirty liar" as their worst. So if you see the banner on our family tree, know that "I think you should shut up you dirty liar", stands for the best of us, and judge us accordingly.
I am sure there are families all over who have had similar discussions, each one with their version of what is unacceptable. They just don't need to tell me that I should like theirs as well as I like mine.
