In the first place, you should not beat her, but talk
sense/logic and tell her why she should NOT say it. (See? 1st step,
you wrong already).
Then, you should find out where she learn the word from, like ask
her, who teach her the word..etc...cuz this could lead to greater
findings...like who is the sickening uncle or brother who teach her
all the bad things... (bet, you never even think about this).
Lastly, you should not beat her anyway, but show your disapproval,
e.g. give a bad face, show that you are angry with her... and say
that if you say that again, you will never buy toys for her
already... (again, think you never do this also).
