My 7 year old daughter thinks that she is so smart, masha’Allah. She really does have a big vocabulary, but from time to time she misuses words. Can someone tell me what’s wrong with the following:

Last night my son came to me whimpering and saying “boo boo”. He looked in distress and started grunting. My daughter said, “Miskeen (this is not the questionable word), he’s exterminated.”
