A woman eats a lot of junk food and her children copy her eating junk food too.
What is the opposite of "role model"?
Can we say "She is a bad role model for her children"?
I found this in the dictionary
a bad/rotten apple: one bad person who has a bad effect on others in a group
Is "She is a rotten apple on her children" the opposite of "She is a bad role model for her children"?
