A Fake Mother In Law is a person who for the sake of her relationship with her son or daughter, is a hypocrite with her daughter or son in law in all situations. This person will gossip and talk behind your back but in-front of her child is a saint.
She is such a Fake Mother In Law! I would never talk to her if it wasn't for my hubby.
