Toxic femininity is using emotional manipulation tactics and lying to achieve your goals. Also, a lack of loyalty, responsibility, morality, conscience or empathy.
Crocodile tears and the victim card are a good example. False accusations, making use of your status as a female to attack others without fear of any retribution, etc.
Also, refusing to bear the consequences of your actions, and expecting others to come and clean up after you as if you are a toddler.
