A friend of mine used to use cats to scare her DD into doing something. Her DD was afarid of them so if she got too far away or something, my friend would say "the cat is going to get you" and her DD would run back looking terrified.
Her DD has got over the fear of cats so now my friend is using 'George'. It is a bloke they saw at a garage and her DD was afraid of him. Now my friend says "George is coming to get you" and her DD runs looking terrified.
To me, she is going to make her DD terrified of men at this rate.
