"an amaenbō (甘えん坊) is someone who relies too much on someone else. It’s usually used to refer to a spoiled child, but an adult can be an amaenbō too, like a man who has to have his tie straightened out for him every morning by his wife, or a girl who expects her boyfriend to pay for every meal and give her lots of gifts."
