Momtacker

Momtacker: noun. A person who blames all of their character traits on their mother. For example, "my mum picks her nose, and so do I". The word was first used by Franklin D. Roosevelt to describe his daughter Anna, who constantly blamed all of her mistakes in the White House administration on her mother, using the catch phrase "That's how mom would have done it." This prompted Eleanor Roosevelt to spend less time at home, so that her daughter wouldn't have any idea how she would have done something.
